Disease progress of soybean bud blight and spatial pattern of diseased plants.
Provedor de dados: 119
Autores: ALMEIDA, A.M.R.; BERGAMIN FILHO, A.; AMORIM, L.
Fourteen epidemics of soybean bud blight, caused by the tobacco streak virus, were monitored in two soybean cultivars ('IAC-4'
and 'FT-10') for two years (1987 and 1988) at Arapoti County, state of Parana, southern Brazil. Disease incidence, based on
different sowing dates, were analyzed for statistical fitness in several growth models. Ten epidemics were better described by the
monomolecular model, while four epidemics were better described by the Gompertz model. The highest final level of disease
incidence was y((f))= 0.6 in 1987 and 0.9 in 1988. There were no significant differences between the cultivars in relation to
susceptibility. Early-crops always presented more disease than late-crops. The spatial patterns of diseased plants also changed...

In the village of Cavunge, located in a dry tropical, semiarid rural region of the state of Bahia, Brazil, a sentinel study on viral
hepatitis is underway. We report on the first part of the study. The objective of this study was to determine the prevalence of
serological markers for hepatitis A, B and C in the village. Cross sectional study. Blood samples were tested for serological
markers of hepatitis A (HAV), B (HBV) and C (HCV) through ELISA-III assay. In HBsAg and anti-HCV carriers, HCV-RNA
and HBV-DNA were checked by PCR. The prevalence of anti-HAV IgG was 83.3% (1,210/1,452), being higher among residents
from the village (87.4%) than in residents from the rural area (79.5%); it also higher among individuals older than 10 years of age.

Provedor de dados: 55
Autores: Andrade-Filho,Antônio de Souza; Figuerôa,Luiz Frederico da Silva; Andrade-Souza,Victor Mascarenhas.
Neurocysticercosis (NCC) is a common parasitic disease in our region, presenting diversity of neurological symptoms and signs.
The present study has as primary objective an evaluation of the NCC's clinical and epidemiological profile within Bahia State, by
means of a prospective study of 220 patients diagnosed from March 1988 to March 1999, with a follow-up of six months. Exams,
such as Computed Cranial Tomography Scan (CT), Cerebral Spine Fluid (CSF) and Electroencephalogram (EEG), were
accomplished in three distinct moments of these patients' evolution: at starting or diagnostic point (zero time), at after-intervention
period (one month after treatment), and at control period (six months after treatment).

Autores: Angeli, J.
After a general presentation of the Thau lagoon together with its geographic location, socio-economic activities linked to shellfish
culture and fishing, this paper investigates the health conditions of the shellfish harvesting areas. I he influence of heavy rainfall
following a prolonged drought period is underlined as a determining factor of the momentary bacterial pollution in the harvesting
areas, leading to a suspension of sales based on analyses relying solely on the detection of faecal coliforms. As of 1989,
bacteriological monitoring was reorganized in the form of a data collection network taking into consideration environmental
assessments of water quality as well as shellfish hygiene in order to protect consumer health. Its extension to the...

Autores: Angelini,Michelle; Stehling,Eliana Guedes; Moretti,Maria Luiza; Silveira,Wanderley Dias da.
Shigella spp., the human pathogen responsible for shigellosis, is highly infectious even at low levels. The incidence rate of
shigellosis varies with geographical distribution, location human development index, and age groups, being higher among children
aged under 5 years. In Brazil, a few works indicate that shigellosis cases are underestimated, with S. flexneri and S. sonnei strains
being the major agents responsible for the shigellosis cases. The present study used pulsed field gel electrophoresis (PFGE) to
investigate the molecular epidemiology of 119 strains of S. sonnei and S. flexneri isolated from shigellosis cases that occurred in
the metropolitan areas of Ribeirão Preto and Campinas Cities, São Paulo Sate, southeast Brazil. The results indicated...

Botrytis blight caused by Botrytis cinerea is an important disease of rose (Rosa hybrida) grown in greenhouses in Brazil. As little
is known regarding the disease epidemiology under greenhouse conditions, pathogen survival in crop debris and as sclerotia was
evaluated. Polyethylene bags with petals, leaves, or stem sections artificially infected with B. cinerea were mixed with crop debris
in rose beds, in a commercial plastic greenhouse. High percentage of plant parts with sporulation was detected until 60 days, then
sporulation decreased on petals after 120 days, and sharply decreased on stems or leaves after 90 days. Sporulation on petals
continued for 360 days, but was not observed on stems after 150 days or leaves after 240 days. Although the fungus...

Arcobacter butzleri isolation from chicken carcasses in Costa Rica is reported for the first time. The isolated strains (P and R)
were presumptively identified by their phenotypic characteristics. Definitive identification was made using a multiplex PCR assay
for the simultaneous detection and identification of Arcobacter butzleri, Arcobacter cryaerophilus and Arcobacter skirrowii. These
first isolations indicate the necessity of further investigation about the prevalence, distribution, ecology and interactions with
human beings of this and other Arcobacter species.

Provedor de dados: 56
Autores: Assunção,L.G.S.; Eloi-Santos,S.M.; Peixoto,S.V.
The measurement of the serum concentration of the acute-phase reactant C-reactive protein (CRP) provides a useful marker in
clinical practice. However, the distribution of CRP is not available for all age and population groups. This study assessed the
distribution of high sensitivity-CRP (hs-CRP) by gender and age in 1470 elderly individuals from a Brazilian community that
participates in the Bambuí Cohort Study. Blood samples were collected after 12 h of fasting and serum samples were stored at
-70°C. Measurements were made with a commercial hs-CRP immunonephelometric instrument. More than 50% of the results
were above 3.0 mg/L for both genders. Mean hs-CRP was higher in women (3.62 ± 2.58 mg/L) than in men (3.03 ± 2.50 mg/L).
This difference was observed...

Implications of infectious diseases and the adrenal hypothesis for the etiology of childhood acute
lymphoblastic leukemia
Provedor de dados: 56
Autores: Azevedo-Silva,F.; Camargo,B.de; Pombo-de-Oliveira,M.S.
Acute leukemia is the most frequent cancer in children. Recently, a new hypothesis was proposed for the pathogenesis of
childhood acute lymphoblastic leukemia (ALL). The so-called "adrenal hypothesis" emphasized the role of endogenous cortisol in
the etiology of B-cell precursor ALL. The incidence peak of ALL in children between 3 to 5 years of age has been well
documented and is consistent with this view. The adrenal hypothesis proposes that the risk of childhood B-cell precursor ALL is
reduced when early childhood infections induce qualitative and quantitative changes in the hypothalamus-pituitary-adrenal axis. It
suggests that the increased plasma cortisol levels would be sufficient to eliminate all clonal leukemic cells originating during fetal
life....

Bonamia ostreae, an intrahemocytic protozoan parasite infecting the oyster Ostrea edulis, is responsible for an endemic disease
affecting all intensive breeding areas of European countries. Epidemiological studies showed variable prevalences, 43% in Galicia
(Spain), from 6% to 32% in France and 45% in the most important area of Ireland. The impact of oyster transfers, handlings, high
densities have been implicated in the disease development but environmental stressors could be more involved than zootechnical
methods. The effect of water temperature, salinity and tidal exposure were particulary examined to assess stress induced changes
and determine physiological, biochemical and immunological state indices of oyster populations, which will contribute to...

provide an audit of birth cohorts from LMIC; and, finally, offer possible future directions for this sphere of research. While the
contribution of birth cohorts from affluent societies to understanding disease aetiology has been considerable, we describe several
reasons to anticipate why the results from such studies might not be directly applied to LMIC. More than any other developing
country, Brazil has a tradition of establishing, maintaining and exploiting birth cohort studies. The clear need for a...

Autores: Berthe, Franck.
Infectious diseases are currently recognised as a major limiting factor to development and sustainability of aquaculture of
molluscs. The study is focused on the European flat oyster, Ostrea edulis and its paramyxean parasite Marteilia refringens. Results
are contributing to the prevention of risk associated to infected stocks imports from endemic zones, by developing molecular
diagnostic tools that are specific, sensible and reliable. Phylogeny and taxonomy of Marteilia refringens, previously impeded by
microscopy limits, were clarified by sequencing the rDNA SSU, small sub-unit in the rRNA gene cluster. These new insights have
practical implications discussed in a pragmatic polyphasic approach involving pathology and epidemiology. This approach led us
to...

Marteiliosis in molluscs: A review
Provedor de dados: 5
Autores: Berthe, Franck; Leroux, Frederique; Adlard, Robert; Figueras, Antonio.
Among mollusc pathogens, paramyxeans are an important group of protistan parasites belonging to the genera Marteilia and
Marteilioides. Martelia refringens and M. sydneyi are of particular concern given their potential impact on mollusc aquaculture
world-wide. Aber disease and QX disease are currently listed by the OIE, the World Organisation for Animal Health. After more
than thirty years of existence in the scientific literature, these organisms still pose questions and research challenges to
investigators. This paper reviews current knowledge of the group and key references. The review was focused on taxonomy,
epidemiology, pathology and potential control methods for these organisms in order to enhance understanding of paramyxean
infection issues in...

Viral Hepatitis C in a leading Brazilian hospital: epidemiological factors and genotyping
Provedor de dados: 58
Autores: Bezerra,Cristianne S.; Lima,José M.C.; Vilar,Janaina L.; Moreira,José L.B.; Frota,Cristiane C.
The hepatitis C virus (HCV) is classified into six different genotypes and their distribution is different throughout the world.
Epidemiologic studies are important to determine several characteristics of the virus, as well as the disease. This study analysed
the prevalence of HCV and its genotypes among patients from a leading hospital in Ceará, which is located in Northeast Brazil. A
total of 119 anti-HCV-seropositive patients, each having previously completed a questionnaire about risk behaviours related to
HCV infection were tested for HCV infection using a qualitative HCV polymerase chain reaction (PCR) assay and genotyping by
restriction fragment length polymorphism (RFLP). The detection was based on amplifying of the non-coding 5' region. Of the

The international view of envenoming in Brazil: myths and realities

Autores: Bochner,Rosany.
Being distant from Brazil's great natural diversity, from its long tradition in the study of snakebites and from the fact that it is one
of the few countries which has a national information system for monitoring incidents involving venomous animals, non-Brazilian
researchers face risks when estimating the incidence of these accidents in the country. The present work offers a critical review of
the main estimates undertaken since 1954. It is interesting to note contradictions between textual and graphic information within
the same article, variations over time in the work of a same researcher and differences among distinct authors, and that all these
issues remain unmentioned or undiscussed. Comparison among such estimates and the data available at the...

The role of petals in development of grey mould in strawberries
Provedor de dados: 102
Autores: Boff,Pedro; Kraker,Joop de; Gerlagh,Mathijs; Köhl,Jürgen.
Studies were conducted in annual crops of strawberry (Fragaria x ananassa) (cv. Elsanta to assess the relative importance of petals
as an inoculum source of grey mould, caused by Botrytis cinerea and to identify during which period of flower and fruit
development the presence of petals has a significant effect on development of grey mould on fruits. In 1998, the incidence of B.
cinerea on flower parts was assessed, and the symptoms of grey mould on fruits were characterised with regards to their starting
point. The incidence of B. cinerea on petals was 65-85% of those flowers that harboured B. cinerea. The starting point of
symptoms was located underneath the sepals in 65-85% of fruits with grey mould, and petals were present at this site in about
50% of...

The aim of this study was to determine the prevalence of Staphylococcus aureus and risk factors for the acquisition of MRSA
(Methicillin Resistant Staphylococcus aureus) as the main cause of skin and soft tissue infections. S. aureus were characterized for
the presence of PVL, TSST-1 and mecA genes. SCCmec typing was carried out in mecA positive strains and PFGE was
performed only in these strains. During the study period, 127 outpatients attending a dermatology clinical the Botucatu Medical
School, a regional tertiary hospital in Botucatu, Sao Paulo, Brazil, were diagnosed with active skin infections. A total 66

background, virulence, and relevance for public health
Provedor de dados: 80
Autores: Bonesso,MF; Marques,SA; Cunha,MLRS.
Staphylococcus aureus and coagulase-negative Staphylococcus (CoNS) are frequently found in nosocomial environments as the
main pathogen in several infections. In 1961, reports of nosocomial S. aureus resistant to methicillin, the drug of choice against
penicillin-resistant strains, required new alternatives and vancomycin started being used to treat infections caused by
methicillin-resistant S. aureus (MRSA). Community-acquired methicillin-resistant S. aureus (CA-MRSA) was first reported in
1990 affecting patients without risk factors for infection with MRSA of hospital origin. MRSA of community origin harbor the
genes responsible for the synthesis of Panton-Valentine leukocidin (PVL), a toxin associated with skin and soft tissue infections
and that...

On the interference of clinical outcome on rabies transmission an perpetuation
Provedor de dados: 80
Autores: Brandão,PE.
Rabies is a viral zoonotic infectious disease that affects mammals and is caused by genotypes/species of the Lyssavirus genus
(Rhabdoviridae, Mononegavirales), with the genotype 1 (classic rabies virus - RABV) being the most prevalent. Despite
continuous efforts, rabies is still an incurable disease that causes thousands of deaths amongst humans worldwide. Due to a wide
range of hosts and the different evolutionary paths of RABV in each host, several host-specific variants have arisen in an ongoing
process. The result of RABV replication in nervous tissues may lead to two opposite clinical outcomes, i.e., paralytic/dumb form
and encephalitic/furious one. The paralytic form creates dead-end hosts mainly amongst herbivores, while the furious form of
the...

Autores: Brunelli,Kátia R.; Dunkle,Larry D.; Sobrinho,Cândido A.; Fazza,Ana C.; Camargo,Luis E. A.
Isolates of Cercospora species from leaves displaying symptoms of grey leaf spot were collected in maize-producing areas of
south-central Brazil in 2001 and 2002. Restriction digests of the internal transcribed spacer region of rDNA detected the presence
of the same two Cercospora species described on maize in the United States, namely C. zeae-maydis and the recently
described species, C. zeina . Genetic variability among isolates was assessed by analysing 104 amplified fragment length
polymorphism loci. Cluster analysis confirmed the genetic separation of isolates into two species with a mean similarity of 35%.
Similarity levels within species were high, averaging 93% and 92% among isolates of C. zeae-maydis and
C. zeina ,
respectively. The mean...

Human coronaviruses (HCoVs) are considered one of the most common respiratory viruses associated with respiratory tract
illnesses. An emergent human coronavirus was identified as the causal agent of an epidemic of severe acute respiratory syndrome
(SARS) during 2002-2003. The severity of the disease combined with its rapid spread requires the continuous surveillance of
coronaviruses in worldwide populations. Epidemiological and clinical data of HCoVs infectious in the Brazilian population are

ABSTRACTStem bleeding disease (resinosis) of coconut palm is caused by Thielaviopsis paradoxa and is very important in the
state of Sergipe, Brazil. Understanding the epidemiological behavior of the disease is essential for establishing more efficient
control strategies. Thus, we characterized the temporal progression and spatial distribution of stem bleeding in a commercial
orchard under conditions of natural infection in the area of Neopolis, Sergipe. Three plots with 729 plants each were selected and
evaluated every two months for stem bleeding incidence. In the temporal analysis, the monomolecular model gave the best fit to
data on disease incidence, as it accurately showed the temporal dynamics of the disease during the experiment period. The
spatial...

Provedor de dados: 58
Autores: Carvalho,Rodolfo Henriques de; Gontijo Filho,Paulo P.
Antimicrobial resistance is a threat to public health worldwide and is associated with higher mortality and morbidity. Despite the
extensive knowledge about this problem, drug resistance has continued to emerge, especially in intensive care units (ICUs). The
objective of this study was to evaluate the frequencies of epidemiologically relevant resistance phenotypes in pathogens isolated
from ventilator-associated pneumonia (VAP), bloodstream infections (BSI) and urinary tract infections (UTI) in patients admitted
in the adult intensive care unit (AICU) of the Clinical Hospital of Federal University of Uberlândia, during an one year period.
Additionally, at the period of the study, the antibiotic consumption in AICU was verified. Coagulase-negative...

Snakebites in Turkey: epidemiological and clinical aspects between the years 1995 and 2004
Provedor de dados: 80
Autores: Cesaretli,Y; Ozkan,O.
The venom of poisonous snakes comprises a complex mixture of several proteins with other less significant constituents, resulting
in principles capable of changing viable tissues. The hemotoxic factor is the main responsible for necrosis and tissue sloughing.
Envenomations are common in rural areas of Turkey caused by snake species that present hepatotoxic venom, which causes local
swelling, ecchymosis and alterations in blood profile. The epidemiological and clinical findings of snake envenomations in
Turkey were evaluated based on data recorded by the National Poison Information Center (NPIC) between 1995 and 2004, in a
total of 550 snakebite cases. The month of peak incidence was June (24.3%) while most incidents occurred in Marmara, Central
Anatolia...

Abstract During the 6th International Conference on Envenomation by Snakebites and Scorpion Stings in Africa held in Abidjan,
from 1 to 5 June 2015, the measures for the management of envenomation were discussed and new recommendations were
adopted by the participants. The high incidence and severity of this affliction were confirmed by several studies conducted in
African countries. The poor availability of antivenom, particularly because of the cost, was also highlighted. Some experiences
have been reported, mainly those regarding the financial support of antivenom in Burkina Faso (more than 90 %) and Togo (up to
60 %) or the mandatory reporting of cases in Cameroon. Key recommendations concerned: improvement of epidemiological

Pseudomonas aeruginosa is an important and frightening microorganism for patients suffering from cancer. Multiresistant P.
aeruginosa (MRPA) may appear as a consequence of exposure to multiple antibiotics or from a breakdown in infection control
practices. This article reports an MRPA outbreak in a cancer treatment centre and the consequent case control study. Mechanical
ventilation was identified as being the main risk factor for developing MRPA colonisation or infection; molecular analysis
confirmed the outbreak. A multifaceted strategy was adopted, involving reinforcing hand-washing practices, contact isolation,
antibiotic restriction and suction devices for mechanically-ventilated patients. MRPA was controlled and the outbreak ended. Such

Bats and their role in human rabies epidemiology in the Americas
Provedor de dados: 80
Autores: Dantas-Torres,F.
Bats are very interesting animals: they are the unique flying mammals, have developed a highly sophisticated echolocation
system, and have become specialized to eat different types of diets. Hematophagous (vampire) bats are those specialized to feed
solely on blood and have served as a source of inspiration for researchers as well as for writers. Vampire bat attacks on humans
have moved from the realm of science fiction to reality in Latin America and bats (including non-hematophagous ones) have
assumed an important role in the transmission of rabies virus to humans. This article discusses the emerging role of bats as rabies
virus transmitters, with particular emphasis on the role of hematophagous bats in the epidemiology of human rabies in Latin
America....

Fusarium head blight (FHB) is a disease of increasing concern in the production of wheat (Triticum aestivum). This work studied
some of the factors affecting the density of airborne Gibberella zeae inoculum. Spore samplers were placed at the edge of a field
in order to observe spore deposition over a period of 45 days and nights in September and October, the period that coincides with
wheat flowering. Gibberella zeae colonies were counted for each period and values transformed to relative density. A stepwise
regression procedure was used to identify weather variables helpful in predicting spore cloud density. In general, a predominant
night-time spore deposition was observed. Precipitation and daily mean relative humidity over 90% were the factors most...

Autores: Diniz-Santos,Daniel R.; Santana,José S.; Barretto,Junaura R.; Andrade,Maria Goreth M.; Silva,Luciana R.
In the few cases of acute childhood diarrhea that require antimicrobial therapy, the correct choice of the drug depends on detailed
previous knowledge of local strains. In order to establish such parameters in our city, we reviewed the results of all 260 positive
stool cultures of children between 0 and 15 years of age during two years at a pediatric tertiary care facility in Salvador, Brazil.
Bacterial strains had been presumptively identified by culturing in selective media and by biochemical testing, and their
antimicrobial susceptibility patterns were automatically detected by the MicroScan Walkaway System. Data about patients' sex
and age, monthly distribution of the cases, pathogens isolated and their antimicrobial resistance patterns were recorded....

This paper provides an ex-ante economic analysis, comparing six alternative control strategies for the eradication of Bluetongue
virus 8 against five incursion scenarios in cattle and sheep populations. The economic analysis assumes a common baseline
unavoidable cost of public and private measures that together contribute to prevention of incursion of BTV8 into Scotland. These
costs continue over the five year horizon of this analysis regardless of whether a BTV8 epidemic ensues in Scotland and their total
present value was found to be approximately £141m over the 5year period. The benefit of this investment is the costs of a BTV8
outbreak avoided; which depends on the time, location and nature of the incursion, on the control strategies adopted to counter...

Campylobacter sp is an important agent that causes foodborne infection, particularly in food of poultry origin. Therefore, the
efficient control of the transmission routes in chicken farms is of outmost importance to prevent it from spreading. In chicken
farms, the main transmission route of this microorganism is horizontal, as the vertical route continues to be the object of
inconclusive researches. The objective of this study was to verify the presence of Campylobacter sp in breeder hens, meconium,
and other organs of day-old chicks derived from these breeders in order to obtain information on vertical transmission.
Microbiological analyses were performed, using cloacal swabs from 279 breeder hens. Positive breeders were segregated, and the

contact with hepatitis B virus (HBV) and 373 million have become chronic carriers. Hepatitis B is a major cause of chronic
hepatitis, cirrhosis and hepatocellular carcinoma, leading to a large number of deaths annually. Both viral factors and the host
immune response have been implicated in the pathogenesis and clinical result of HBV infection. Many Brazilian cities, including
the cities of the northern region of the state of Espírito Santo are located in regions with little health infrastructure. Our study
performed an epidemiological analysis of cases of Hepatitis B in São Mateus, using methodology of Geographic Information

A large waterborne outbreak of infection that occurred during August 2000 in a local community in France was investigated
initially via a rapid survey of visits to local physicians. A retrospective cohort study was then conducted on a random cluster
sample of residents. Of 709 residents interviewed, 202 (28.5%) were definite cases (at least three liquid stools/day or vomiting)
and 62 (8.7%) were probable cases (less than three liquid stools/day or abdominal pain). Those who had drunk tap water had a
three-fold increased risk for illness (95% CI 2.4-4.0). The risk increased with the amount of water consumed (chi-square trend: p
< 0.0001). Bacteriological analyses of stools were performed for 35 patients and virological analyses for 24 patients....

Exposure to aflatoxins (AFs) in the diet may favour the development of hepatocellular carcinoma (HCC) and the acute
exacerbation of hepatitis in chronic hepatitis B virus (HBV) carriers. Measurement of biomarkers such as aflatoxin M1 (AFM1), a
metabolite of aflatoxin B1 (AFB1), in urine allows for the assessment of populations exposed to aflatoxins. The aim of this study
was to investigate the occurrence of aflatoxin M1 in the urine of HBV carrier and non-carrier patients. One group included 43
randomly selected HBV carriers treated at two hospitals in the city of Maringa, Brazil, from March to June 2008. Control group
consisted of 29 healthy adult volunteers with anti-HBs positive and HBsAg negative test results. Detection of AFM1 was

"Summer Syndrome" in Litopenaeus stylirostris in New Caledonia: Pathology and epidemiology of
the etiological agent, Vibrio nigripulchritudo
Provedor de dados: 5
Autores: Goarant, Cyrille; Ansquer, Dominique; Herlin, Jose; Domalain, David; Imbert, Frederic; De Decker, Sophie.
The Summer Syndrome is a new shrimp disease that has been affecting a shrimp growout farm in New Caledonia since end of
1997. It was recognized to be caused by a systemic vibriosis due to Vibrio nigripulchritudo. This new disease turned out almost
immediately enzootic in the shrimp farm involved and has affected all its crops ever since. Since the year 2000, V.
nigripulchritudo strains have been found in several shrimp farms, although Summer Syndrome is still limited to one particular
area, affecting, since 2003, two adjoining farms. As part of a multidisciplinary research program, a high-frequency survey was
carried out during the summer 2002-2003 in two shrimp farms: one affected farm and another one in which pathogenic strains
could be isolated but...

A collection of 57 isolates of Vibrio nigripulchritudo from either diseased or healthy shrimp and from shrimp farms environment
was studied in order to gain a better understanding of the epidemiology of this pathogen, notably isolated from two distinct shrimp
disease complexes. Molecular typing using two different techniques, arbitrarily primed PCR (AP-PCR) and multi-locus sequence
typing (MLST), studied together with experimental pathology data allowed a relevant epidemiological insight into this possibly
emerging pathogen. Additionally, results obtained with the two molecular typing techniques were congruent and allowed
discriminating the strains associated with the "Summer Syndrome" from strains isolated from other contexts, especially the other

Jointly-Determined Livestock Disease Dynamics and Decentralized Economic Behavior

Richard D.
We develop a dynamic model of livestock disease and decentralized economic behavior as a jointly-determined system. By
accounting for feedbacks between behavioral choices and disease outcomes we capture the endogenous nature of infection risks.
We consider government mandated testing of livestock herds and how private biosecurity incentives are affected by the structure
of disease eradication polices. How well disease control policies are targeted affects their effectiveness and may result in farmers
substituting government testing and disease surveillance for private biosecurity. Numerical simulation results demonstrate that
failing to account for feedbacks between disease and economic dynamics may underestimate the level of infection. Not accounting

The spread of major diseases of molluscs around the world and the increase of transfers need the development of adapted
prophylactic strategies and the increase of research in epidemiology, immunology and genetics. The prophylactic strategies must
be based on common laws with the establishment of a list of declarable pathogens, with basic sampling rules (sample size,
frequency, definition of geographical areas) and with reglementation of the internal transfers. Moreover, specific adapted
diagnosis should be developed to increase the sanitary control performance (e.g. ELISA test, DNA probe, cell culture). In the case
of an infectious disease the epidemiology studies should be concerned, the relationship between the culture techniques and the

This study investigated the occurrence of canine distemper virus (CDV) by evaluating the presence of viral RNA within urine
samples of dogs from Uberlândia, MG, with clinical manifestations suggestive of infection by CDV by targeting the CDV N gene.
Of the clinical samples collected ( n =33), CDV viruria was detected in 45.5%. Five dogs died spontaneously; all had
characteristic CDV-associated histopathological alterations and demonstrated CDV viruria. Statistical analyses revealed that the
age, gender, breed, or the organ system of the dog affected had no influence on the occurrence of canine distemper. Myoclonus
and motor incoordination were the most significant neurological manifestations observed. A direct association was observed

Melioidosis, which is caused by the bacterium Burkholderia pseudomallei, is a potentially fatal tropical infection, little known
outside its main endemic zone of Southeast Asia and northern Australia. Though it has received more attention in recent years on
account of its claimed suitability as a biological weapon agent, the principal threat from melioidosis is a result of naturally
occurring events. Occasional case clusters, sporadic cases outside the known endemic zone and infections in unusual demographic
groups highlight a changing epidemiology. As melioidosis is the result of an environmental encounter and not person-to-person
transmission, subtle changes in its epidemiology indicate a role environmental factors, such as man-made disturbances of soil...

outbreak, adapted to local climatic conditions and negatively diagnosed for WSSV and infectious hypodermal and hematopoietic
necrosis virus (IHHNV), and to evaluate if this strategy is a viable alternative for production in Santa Catarina, Brazil. A total of
800 males and 800 females were phenotypically selected in a farm pond. Nested-PCR analyses of 487 sexually mature females
and 231 sexually mature males showed that 63% of the females and 55% of the males were infected with IHHNV. Animals free of
IHHNV were tested for WSSV, and those considered double negative were used for breeding. The post-larvae produced were
stocked in nine...

ABSTRACTThe aim of this work was to develop and evaluate an indirect enzyme-linked immunosorbent assay (ELISA) and
made a serological screening for specific antibodies to BoHV-4. Bovine serum samples were collected from different Brazilian
states and evaluated for the presence of antibodies for BoHV-4 and BoHV-1. The serological results obtained showed that the
indirect ELISA assay could be applied for the detection of specific antibodies for BoHV-4. The ELISA test allowed concluding
that BoHV-4 is present in bovines in every Brazilian state from which serum samples were collected. The ELISA assay here
standardized proved to be useful for the epidemiological studies and showed a positivity range from 1.8 to 66% in Brazil.

Scorpion stings are a public health problem in the Maghreb region. In Algeria, epidemiological data were collected over the past
twenty years by the Algerian health authorities. This study is an analysis of morbidity and mortality data collected from 2001 to
2010. Annual incidence and mortality due to scorpion envenoming were 152 ± 3.6 stings and 0.236 ± 0.041 deaths per 100,000
people (95% CI), respectively. The risk of being stung by a scorpion was dramatically higher in southern areas and central
highlands due to environmental conditions. Incidence of envenoming was especially higher in the adult population, and among
young males. In contrast, mortality was significantly higher among children under 15 years, particularly ages 1-4. Upper limbs

Gray mold caused by Botrytis cinerea limits grape production in Chile
Provedor de dados: 118
Autores: Latorre,Bernardo A; Elfar,Karina; Ferrada,Enrique E.
Gray mold (GM) caused by Botrytis cinerea is a major disease of grapes (Vitis vinifera) that substantially reduces the yield and
quality of grape production in temperate and humid regions of the world. B. cinerea is a necrotrophic fungus that attacks the
non-lignified aerial organs of grapes; in particular, berries are highly susceptible during ripening. The polycyclic nature and
exponential progress exhibited by GM at the beginning of the its epidemic, as well as the abundant inoculum production, the high
dissemination efficiency, the wide host range and the high genetic variability of B. cinerea, explain the difficulties encountered in
attempting to control GM. At present, integrated disease management, including cultural and chemical control, is the...

French mollusc production is based mainly on the Pacific cupped oyster, Crassostrea gigas. Since 1991, annual mass mortality of
juveniles has been reported during summer months. These recurring episodes concern professionals who fear that like Portugese
oyster, C. angulata, C gigas could in turn disappear following one of these epizooties. Previously, bacteriological analysis of
moribund oyster juveniles yielded an isolate of a Vibrio splendidus biovar H strain, named TNEMF6. This isolate was
demonstrated to be pathogenic to Crassostrea gigas spat by experimental challenge. To study the association between summer
oyster mortality and presence of TNEMF6 cluster strains, Vibrionaceae fauna were isolated from infected spat along the French
Atlantic coast...

Sporothrix schenckii and sporotrichosis
Provedor de dados: 42
Autores: Lopes-Bezerra,Leila M.; Schubach,Armando; Costa,Rosane O.
For a long time sporotrichosis has been regarded to have a low incidence in Brazil; however, recent studies demonstrate that not
only the number of reported cases but also the incidence of more severe or atypical clinical forms of the disease are increasing.
Recent data indicate that these more severe forms occur in about 10% of patients with confirmed diagnosis. The less frequent
forms, mainly osteoarticular sporotrichosis, might be associated both with patient immunodepression and zoonotic transmission of
the disease. The extracutaneous form and the atypical forms are a challenge to a newly developed serological test, introduced as
an auxiliary tool for the diagnosis of unusual clinical forms of sporotrichosis.

Mucormycosis usually presents as a progressive infection with significant angio-invasion. Mucormycosis due to Mucor irregularis
(formerly Rhizomucor variabilis var. variabilis), however, is exceptional in causing chronic cutaneous infection in
immunocompetent humans, ultimately leading to severe morbidity if left untreated. More than 90 % of the cases known to date
were reported from Asia, mainly from China. The nearest neighbour of M. irregularis is the saprobic species M. hiemalis. The aim
of this study was to evaluate the taxonomic position, epidemiology, and intra- and inter-species diversity of M. irregularis based
on 21 strains (clinical n = 17) by multilocus analysis using ITS, LSU, RPB1 and RPB2 genes, compared to results of cluster
analysis with...

INTRODUCTION: methicillin- and also vancomycin (glycopeptide)-resistant Gram-positive organisms have emerged as an
increasingly problematic cause of hospital-acquired infections, also spreading into the community. Vancomycin (glycopeptide)
resistance has emerged primarily among Enterococci, but the MIC values of vancomycin for the entire Staphylococcus species are
also increasing worldwide. MATERIAL AND METHODS: the aim of our review is to evaluate the efficacy and tolerability of
newer antibiotics with activity against methicillin-resistant and glycopeptide-resistant Gram-positive cocci, on the ground of our
experience at a tertiary care metropolitan Hospital, and the most recent literature evidences in this field. RESULTS:

Abstract: The objective of this work was to monitor traits of the life cycle of Pseudomonas savastanoi pv. phaseolicola, in order to
better understand the outbreak of bean halo blight, originating from a bacterial population in asymptomatic plants. Five
experiments were conducted in the field, in greenhouses, and in humidity chambers. Changes in population size were evaluated in
three field plantings, by introducing the bacteria in contamination focal points and observing the weather conditions favoring an
outbreak. The dispersion of the bacteria in the field was followed by isolation and Bio-PCR analysis. Two assays were conducted
in greenhouses and humidity chambers to evaluate the effect of leaf age on disease expression and the relationship between...

Autores: Meireles,MV; Roberto,LO; Riera,RF.
There are few reports concerning the epidemiology of Eimeria praecox and Eimeria mitis in Brazil. In the present experiment, the
polymerase chain reaction (PCR) was used to identify these species in 156 samples of broiler chicken feces from several Brazilian
states and the Federal District. Oocysts present in feces samples were purified by sodium chloride flotation followed by addition
of DNAzol reagent (Invitrogen®) for extraction of genomic DNA. DNA was precipitated and stored following DNAzol reagent
manufacture's instructions. The primers and PCR conditions were as described by Schnitzler et al. (1999). In the 156 field samples
analyzed by PCR, 70 and 45 were positive for E. praecox and E. mitis, respectively. In this study we have shown that DNA...

The role of diffusely adherent Escherichia coli (DAEC) in diarrheal disease has been controversial. However, DAEC strains were
recently implicated in diarrheal disease in developing countries. To clarify whether DAEC are prevalent among sporadic cases of
diarrheal illness in Osaka City, Japan, E. coli strains isolated between July 1997 and March 2000 during diarrheagenic E. coli
(DEC) investigation were retrospectively examined. DAEC strains were recognized among 41 (4.4%) of 924 patients and formed
the biggest subgroup of DEC. Previously, we reported that some DAEC strains caused epithelial cells to secrete as much IL-8 as
enteroaggregative E. coli strains did. In this study, we attempted to evaluate epidemiologically whether the ability of DAEC to

Autores: Michereff,Sami J; Noronha,Marissônia A; Lima,Gaus SA; Albert,Ígor CL; Melo,Edilaine A; Gusmão,Luciana O.
The downy mildew, caused by Pseudoperonospora cubensis, is an important melon disease in Northeast Brazil. Considering the
lack of standard methods for its assessment, a diagrammatic scale was developed with 2, 4, 8, 16, 32, 64, 82, and 96% of affected
leaf area. The scale was then checked for its accuracy, precision, and reproducibility in estimating downy mildew severity. The
diagrammatic scale was validated by eight disease raters; using 50 leaves with different severity levels, previously measured using
the software Assess®. Two evaluations were performed on the same set of leaves, but in a different sequence order, by the same
raters, within a 15-day interval. The accuracy and precision of each rater was determined by simple linear regression between...

The Vibrio splendidus clade has previously been associated with epidemic outbreaks of various aquatic animals, as in the case of
the cupped oyster, Crassostrea gigas. To investigate whether involved strains could present a clonal origin and to identify possible
alternative background carriage animals or zooplankton, a large epidemiological survey was conducted on isolates of the
splendidus clade. For this purpose, Vibrio strains were isolated from various samples including oysters, mussels, sediments,
zooplankton, and sea water on the basis of a North/South gradient of the European sea water zone (Ireland, The Netherlands,
France, Italy, and Spain). A total of 435 isolates were successfully associated to the V. splendidus clade using real time
polymerase...

Ferreira Neto,José Soares.
In the southern region of Mato Grosso do Sul state, Brazil, a foot-and-mouth disease (FMD) epidemic started in September 2005.
A total of 33 outbreaks were detected and 33,741 FMD-susceptible animals were slaughtered and destroyed. There were no
reports of FMD cases in other species than bovines. Based on the data of this epidemic, it was carried out an analysis using the
K-function and it was observed spatial clustering of outbreaks within a range of 25km. This observation may be related to the
dynamics of foot-and-mouth disease spread and to the measures undertaken to control the disease dissemination. The control
measures were effective once the disease did not spread to farms more than 47 km apart from the initial outbreaks.

Candidiasis has become an important concern for clinical practice, especially with the increasing incidence of
immunocompromised patients. In this scenario, the development resistance to fluconazole presents a challenge for treating these
opportunistic infections. The aim of this study was to evaluate some epidemiology features of Candidainfections in a Brazilian
University Hospital using data, previously unavailable. We observed that 44% of the 93 clinical isolates tested, belonged to
Candida albicansspecies and 56% belonged to non-Candida albicansspecies (mainly Candida tropicalis and Candida glabrata).
Most strains were isolated from urine samples where C. albicans was predominantly detected. 29 strains presented a fluconazole

Rearing practices identified as risk factors for ostreid herpesvirus 1 (OsHV-1) infection in Pacific
oyster Crassostrea gigas spat
Provedor de dados: 5
Autores: Normand, Julien; Blin, Jean-louis; Jouaux, Aude.
Early detection of Pacific oyster spat infected with ostreid herpesvirus 1 (OsHV-1) could prevent introduction of OsHV-1-infected
individuals into farming areas or onshore rearing facilities, thus reducing the risk of infection of naïve oysters in such production
systems. Experiments were conducted on several hundred oyster spat provided by producers in order to examine whether early
rearing practices could be considered as potential risk factors for (1) OsHV-1 infection as detected by molecular methods and (2)
spat mortality experimentally induced through thermal challenge. Spat groups collected on oyster beds and hatchery spat reared in
growout areas during summer exhibited higher viral DNA contamination and mortalities during the trial than spat kept in...

The Mathematical Biology of Human Infections
Provedor de dados: 7
Autores: Nowak, Martin A; Institute for Advanced Study; [email protected].
Humans are constant victims of infectious diseases. Biomedical research during this century has led to important insights into the
molecular details of immune defense. Yet, many questions relating to disease require a quantitative understanding of the complex
systems that arise from the nonlinear interactions between populations of immune cells and infectious agents. Exploration of such
questions has lead to a newly emerging field of mathematical biology describing the spread of infectious agents both within and
between infected individuals. This essay will discuss simple and complex models of evolution, and the propagation of virus and
prion infections. Such models provide new perspectives for our understanding of infectious disease and provide guidelines...

In the present study, 470 children less than 72 months of age and presenting acute diarrhea were examined to identify associated
enteropathogenic agents. Viruses were the pathogens most frequently found in stools of infants with diarrhea, including 111 cases
of rotavirus (23.6% of the total diarrhea cases) and 30 cases of adenovirus (6.3%). The second group was diarrheogenic
Escherichia coli (86 cases, 18.2%), followed by Salmonella sp (44 cases, 9.3%) and Shigella sp (24 cases, 5.1%). Using the PCR
technique to differentiate the pathogenic categories of E. coli, it was possible to identify 29 cases (6.1%) of enteropathogenic E.
coli (EPEC). Of these, 10 (2.1%) were typical EPEC and 19 (4.0%) atypical EPEC. In addition, there were 26 cases (5.5%) of...

Classification errors, selection bias, and uncontrolled confounders are likely to be present in most epidemiologic studies, but the
uncertainty introduced by these types of biases is seldom quantified. The authors present a simple yet easy-to-use Stata command
to adjust the relative risk for exposure misclassification, selection bias, and an unmeasured confounder. This command
implements both deterministic and probabilistic sensitivity analysis. It allows the user to specify a variety of probability
distributions for the bias parameters, which are used to simulate distributions for the bias-adjusted exposure–disease relative risk.
We illustrate the command by applying it to a case–control study of occupational resin exposure and lung-cancer deaths. By...

Due to a lack of national information about cull dairy cows, the USDA's National Animal Health Monitoring System (NAHMS)
Dairy '96 Study investigated culling management practices. Operations included in the study represented 83.1 percent of U.S. milk
cows. Most dairy cows were culled for reasons associated with their inability to profitably produce high-quality milk and calves;
reasons for culling were not usually related to ill health or systemic disease. Results showed that almost all cull dairy cows in the
US are intended for beef slaughter, as only about 4.4 percent were sent to other dairy operations. Nearly 77 percent of cows
intended for beef slaughter were sent to markets, auctions, and sale barns, while 22 percent were sent straight to slaughter...

evaluated in this study. Mesobuthus eupeus (M. eupeus) plays a role on 25.8% of the scorpionism cases. This study also showed
that intoxications caused by M. eupeus in the southeast of Anatolia region were seen in hot months of the summer, especially on
July. Females and people above 15 years old were mostly affected and stung on extremities. Intense pain in the affected area was
observed in 98.7% cases, hyperemia in 88.8%, swelling in 54.6%, burning in 19.7%, while numbness and itching were seen less
frequently. In our study, the six most frequently observed symptoms were local pain, hyperemia, swelling, burning, dry mouth,
thirst,...

Evaluation of scorpion sting incidence in turkey
Provedor de dados: 80
Autores: Ozkan,O.; Uzun,R.; Adiguzel,S.; Cesaretli,Y.; Ertek,M.
Scorpion stings are common in Turkey due to its geographical location, climate and socioeconomic structure. Scorpion
envenomation cases are a considerable public health problem in all regions of the country. Important health-threatening scorpions
in Turkey are Androctonus crassicauda, Leiurus quinquestriatus, Mesobuthus gibbosus and M. eupeus, all of which belong to the
Buthidae family. They are described to be potentially dangerous to humans. So far, there is no study about scorpion sting
incidence covering all geographical regions of Turkey; therefore, in this study, we analyzed the frequency of scorpion sting cases
in the country. A total of 24,261 scorpion sting cases were reported during 2005. Most of which (about 80%) occurred in the
Southeastern...

This report presents a modeling framework in which epidemiological model results are integrated with an economic model of the
U.S. agricultural sector to enable estimation of the economic impacts of outbreaks of foreign-source livestock diseases. To
demonstrate the model, the study assessed results of a hypothetical outbreak of foot-and-mouth disease (FMD). The modeling
framework includes effects of the FMD episode on all major agricultural products and assesses these effects on aggregate supply,
demand, and trade over 16 quarters. Model results show a potential for large trade-related losses for beef, beef cattle, hogs, and
pork, though relatively few animals are destroyed. The swine and pork sectors recover shortly after assumed export restrictions

Abstract
Background Hepatitis E virus (HEV) can cause chronic infection with rapid progression to liver cirrhosis in
immunocompromised patients. HEV seroprevalence in patients with Schistosoma mansoni in Brazil is unknown. We evaluated
the prevalence of past or present HEV infection in schistosomiasis patients in Recife, Pernambuco, Brazil. A total of 80 patients
with Schistosoma mansoni were consecutively enrolled in a cross-sectional study. Serum samples were tested for the presence of
anti-HEV IgG antibodies by enzyme immunoassay (Wantai anti-HEV IgG, Beijing, China) and for the presence of HEV RNA
using real time reverse transcriptase-polymerase chain reaction with primers targeting the HEV ORF2 and ORF3. Clinical and
laboratory tests as well as...

Provedor de dados: 5
Autores: Pernet, Fabrice; Lagarde, Franck; Le Gall, Patrik; Roque D'Orbcastel, Emmanuelle.
We present the first large-scale, high-resolution spatial and temporal pattern of disease mortality caused by Ostreid herpesvirus 1
(OsHV-1) that has affected Pacific oyster Crassostrea gigas in France every year since 2008, in relation to local farm use.
Mortality was monitored in healthy oyster spat deployed at 106 locations in the Thau Mediterranean lagoon during the epizootic
that occurred in spring 2011. We conducted a field survey of farming practices in the areas where the sentinel oysters were placed
before the epizootic. We found that the risk of disease mortality in sentinel oysters was higher within the bivalve farming area
than outside it, suggesting that the infection pressure is much higher in areas with intensive farming activity. The risk...

Autores: Petton, Bruno; Boudry, Pierre; Alunno-bruscia, Marianne; Pernet, Fabrice.
Mortalities of oyster Crassostrea gigas seed associated with ostreid herpesvirus OsHV-1 μVar have been observed in many
oyster-producing countries since 2008. The present study, comprised of 4 complementary experiments, aimed to identify factors
associated with disease-induced oyster mortality in order to propose mitigation strategies. Our first experiment compared survival
of oysters from natural spatfall with others sampled from nurseries, after thermal elevation in the laboratory from <14 to 21°C.
A total of 60% of the tested wild seed batches (n = 51) were infected by OsHV-1, exhibited mortality and were able to transmit
the disease to cohabited naïve oysters. Comparatively, only 1 out of the 32 tested batches sampled from nurseries presented...

Six upland rice cultivars were evaluated under two nitrogen levels (10 kg and 60 kg N/ha) for blast control based on slow leaf and
panicle blast characteristics in field experiments conducted during three consecutive years. The criteria for measuring slow
blasting resistance were area under disease progress curve (AUDPC), maximum severity during disease progress (Ymax) and the
rate of increase until the disease reaches maximum ('ymax.). There was a high positive correlation among the criteria utilized. The
control of leaf blast in improved rice cultivars (Cuiabana, Centro America, Guarani, Rio Paranaiba) ranged from 36 to 56% for 10
kg/ha of N and from 19 to 49% for 60 kg/ha of N over the susceptible checks (IAC 47, IAC 165). The effect of slow blasting...

The aim of this paper was to study some epidemiological aspects of the infection by Brucella abortus in risk occupational groups
in the microregion of Araguaína, Tocantins. For antibody research, 645 serum samples were analyzed by the complement fixation
test (CF). A 4.0% frequency was found (26/645) in patients' serum and among those 4.1% (23/551) were slaughterhouses
employees and 8.1% (3/37) rural workers. Of the total positive samples, three (2.0%) were women and 23 (4.7%) men; ten (2.9%)
were between the ages of 18 and 30, six (3.4%) between 31 and 40, and nine (8.0%) were above 41 years of age. Risk factors for
brucellosis in the study groups were age, background (OR = 2.45; CI 95% = 0.98 to 6.10) and previous work conducted with

Differences in age and sex distribution as well as FAB (French-American-British classification) types have been reported for
acute leukemias in several countries. We studied the demographics and response to treatment of patients with acute myeloid
leukemia (AML) and acute lymphoblastic leukemia (ALL) between 1989 and 2000 in Teresina, Piauí, and compared these results
with reports from Brazil and other countries. Complete data concerning 345 patients (230 ALL, 115 AML) were reviewed. AML
occurred predominantly in adults (77%), with a median age of 34 years, similar to that found in the southeast of Brazil but lower
than the median age in the United States and Europe (52 years). FAB distribution was similar in children and adults and FAB-M2

Epidemiology of recurrent venous thrombosis
Provedor de dados: 56
Autores: Ribeiro,D.D.; Lijfering,W.M.; Barreto,S.M.; Rosendaal,F.R.; Rezende,S.M.
Venous thrombosis, including deep vein thrombosis and pulmonary embolism, is a common disease that frequently recurs.
Recurrence can be prevented by anticoagulants, but this comes at the risk of bleeding. Therefore, assessment of the risk of
recurrence is important to balance the risks and benefits of anticoagulant treatment. This review briefly outlines what is currently
known about the epidemiology of recurrent venous thrombosis, and focuses in more detail on potential new risk factors for venous
recurrence. The general implications of these findings in patient management are discussed.

The objective of the present study was to investigate factors associated with cesarean sections in two cities located in different
regions of Brazil and to determine factors that explain the higher cesarean section rate in the more developed city, Ribeirão Preto,
compared to the less developed one, São Luís. Data from two cohort studies comprising 2846 women in Ribeirão Preto in 1994,
and 2443 women in São Luís in 1997/1998 were used. Adjusted and non-adjusted risk estimates were calculated using a Poisson
regression model. The cesarean section rate was 33.7% in São Luís and 50.8% in Ribeirão Preto. Adjusted analysis in a joint
sequential model revealed a 51% higher risk of cesarean section in Ribeirão Preto compared to São Luís (prevalence rate ratio...

The spatial dynamics of Citrus Variegated Chlorosis (CVC) was studied in a five-year old commercial orchard of 'Valencia' sweet
orange (Citrus sp.) trees, located in the northern region of the state of São Paulo, Brazil. One thousand trees were assessed in 25
rows of 40 trees, planted at 8 x 5 m spacing. Disease incidence data were taken beginning in March 1994 and ending in January
1996, at intervals of four to five months. Disease aggregation was observed through the dispersion index analysis (Ib), which was
calculated by dividing the area into quadrants. CVC spatial dynamics was examined using semivariogram analysis, which
revealed that the disease was aggregated in the field forming foci of 10 to 14 m. For each well-fitted model, a kriging map was...

Background Toxoplasmosis is a zoonosis caused by an obligate intracellular parasite, Toxoplasma gondii, which affects
warm-blooded animals including humans. Its prevalence rates usually vary in different regions of the planet. Methods In this
study, an analysis of the seroprevalence of toxoplasmosis among Brazilian students was proposed by means of IgG specific
antibodies detection. The presence of anti-Toxoplasma gondiiantibodies by indirect fluorescent antibody test (IFAT) was also
evaluated in order to compare it with enzyme-linked immunosorbent assay (ELISA) and to assess the use of
2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) and o-phenylenediamine dihydrochloride chromogens. Results

Epidemiological studies show that human papillomaviruses (HPV) are strongly related to cervical cancer and cervical
intraepithelial neoplasias (CIN). Unlike the case for women, there are no consistent data on the natural history of HPV in the male
population even though these viruses are prevalent in males. We carried out a prospective study to assess the prevalence of HPV
in males as well as the factors that determine such infections in 99 male sexual partners of women with CIN. The genitalia of the
males were physically examined and subjected to peniscopy for the collection of scrapings which were subjected to the
polymerase chain reaction and restriction fragment length polymorphism to detect HPV. Of the 99 males sampled, 54 (54.5%)
were positive for...

prototype sequence within the L1 gene. Comparative nucleotide sequence analyses of these viruses have elucidated some features
of their phylogenetic relationship. In addition, human papillomavirus intratype variability has also been used as an important tool
in epidemiological studies of viral transmission, persistence and progression to clinically relevant cervical lesions. Until the
present, little has been published concerning the functional significance of molecular variants. It has been shown that nucleotide
variability within the long control region leads to differences in the binding affinity of some cellular transcriptional...

Ventilator-associated pneumonia (VAP) is the most commonly-acquired infection in patients in intensive care units. We analyzed
epidemiological and microbiological characteristics and the outcome, in a cohort of critically-ill patients with confirmed diagnosis
of VAP. All patients who had been on mechanical ventilation (MV) for more than 48 hours were included in our study; material
collection for microbiological analysis was done within the first 24 hours after beginning treatment or after changing antibiotics.
There were 55/265 (20.7%) VAP cases diagnosed, at a rate of 21.6 episodes per 1,000 days of mechanical ventilation. Mean age
of the patients was 66 years, with a mean APACHE II score of 26.7 + 7.0; male patients were more prevalent. The mortality...

Snakebite is a common occupational health hazard among Sri Lankan agricultural workers, particularly in the North Central
Province. Viperine snakes, mainly Russell’s viper envenomation, frequently lead to acute renal failure. During the
last two decades, an agrochemical nephropathy, a chronic tubulointerstitial disease has rapidly spread over this area leading to
high morbidity and mortality. Most of the epidemiological characteristics of these two conditions overlap, increasing the chances
of co-occurrence. Herein, we describe four representative cases of viperine snakebites leading to variable clinical presentations, in
patients with chronic agrochemical nephropathy, including two patients presented with acute and delayed anuria. These cases...

A molecular epidemiological survey on Theileria orientalis was conducted in a cattle population of Fujian province in China. The
screening polymerase chain reaction assay showed that 23 (45%) of 51 blood samples were positive for T. orientalis. DNA
sequencing of the major piroplasm surface antigen-encoding gene indicated the presence of 3 different genotypes in the study
area(types 1，2，and 5) and identified T. orientalis types 1 and 2 as the major genotypes in the sample population. Because type
2 (Ikeda type in Japan) has been recognized as a relatively virulent genotype of T. orientalis，control and preventive measures to
minimize the incidence of infectious diseases among cattle bred in China are necessary.

Overview of Zika virus (ZIKV) infection in regards to the Brazilian epidemic
Provedor de dados: 56
Autores: Slavov,S.N.; Otaguiri,K.K.; Kashima,S.; Covas,D.T.
Zika virus (ZIKV), a mosquito-borne flavivirus, belongs to the Flaviviridae family, genus Flavivirus. ZIKV was initially isolated
in 1947 from a sentinel monkey in the Zika forest, Uganda. Little clinical importance was attributed to ZIKV, once only few
symptomatic cases were reported in some African and Southeast Asiatic countries. This situation changed in 2007, when a large
outbreak was registered on the Yap Island, Micronesia, caused by the Asian ZIKV lineage. Between 2013 and 2014, ZIKV spread
explosively and caused many outbreaks in different islands of the Southern Pacific Ocean and in 2015 autochthonous transmission
was reported in Brazil. Currently, Brazil is the country with the highest number of ZIKV-positive cases in Latin America.

In 1999, on the occasion of the application of the first vaccine dose during the state vaccination campaign against hepatitis B virus
(HBV), 390 individuals from the town of Rio Branco, Acre, aged two or more years were selected for the determination of the
seroprevalence of HBV and HCV. HBV markers (HBsAg, anti-HBs, and anti-HBc IgG) were determined on this occasion and
anti-HBs antibodies were also assessed 30 days after the third vaccine dose. At the time of vaccination, 39% of the individuals
were still susceptible to HBV, while 61% presented serologic evidence of previous HBV contact or previous vaccination. The
individuals with previous HBV contact were significantly older (p<0.001) than those without HBV markers. Of the 192

Japanese encephalitis virus (JEV) causes Japanese encephalitis, which is a leading form of viral encephalitis in Asia, with around
50,000 cases and 10,000 deaths per year in children below 15 years of age. The JEV has shown a tendency to extend to other
geographic regions. Case fatality averages 30% and a high percentage of the survivors are left with permanent neuropsychiatric
sequelae. Currently, there is no cure for JEV, and treatment is mainly supportive. Patients are not infectious, but should avoid
further mosquito bites. A number of antiviral agents have been investigated; however, none of these have convincingly been
shown to improve the outcome of JEV. In this review, the current knowledge of the epidemiology and the pathogenesis of this

and arid areas with a large rural population. In view of this alarming situation, we have conducted this investigation on scorpion
envenomation in the Haouz and Souss plains between 1994 and 1998. Preliminary results have shown a high rate of scorpion
envenomation with several deaths. With the exception of Scorpio maurus, the suspected species are generally anthropophilous,
which belong to the Androctonus genera of the Buthidae family. The Buthidae family is responsible for 96.93% of the
envenomings. In the southwestern Morocco, the death rate is of about 3.84%. The Androctonus mauretanicus is responsible for
60% of deaths. We...

Cervical cancer is an important health problem in women living in developing countries. Infection with some genotypes of human
papillomavirus (HPV) is the most important risk factor associated with cervical cancer. Little information exists about HPV
genotype distribution in rural and suburban regions of Mexico. Thus, we determined the prevalence of HPV genotypes in women
from Tlaxcala, one of the poorest states in central Mexico, and we evaluated age infection prevalence and risk factors associated
with cervical neoplasm. A cross-sectional study was conducted in 236 women seeking gynecological care at the Mexican Institute
for Social Security in Tlaxcala, Mexico. Cervical scrapings were diagnosed as normal, low-grade, and high-grade squamous...

Knowledge of genotype distribution of hepatitis C virus (HCV) has clinical importance due to genotype 1 lower response to
treatment compared with genotypes 2 and 3. The goal of this survey was to describe clinical and laboratorial profiles of patients
with chronic hepatitis C (CHC) in the State of Piauí, as well as to expand the overall awareness of the distribution of HCV
genotyping in Northeast of Brazil. A retrospective cross-sectional study was carried out between April 1999 and August 2005. A
total of 153 patients were included, 119 (77.8%) males and 34 (22.2%) females; mean age = 48.01 ± 9.11 years. We observed a
homogeneous distribution between genotypes 1 (50.0%) and 3 (49.0%), while the most frequent subtype noticed was 3a (49.0%).

The association of HIV infection and hepatitis C virus (HCV) infection often occurs because both viruses share the same
transmission routes, increasing the possibility of HIV/HCV coinfection. World prevalence greater than 30% of coinfected cases is
estimated, and it can reach 90% depending on the transmission route. With the aim of determining the frequency and profile of
HIV/HCV coinfected patients, a descriptive analysis was carried out with patients with HIV/AIDS whose serology was positive
for hepatitis C virus (HCV), cared for at the Fundação de Medicina Tropical do Amazonas from 2000 to 2007. In the present
study, of the 2,653 AIDS cases notified in SINAN, 1,582 patients underwent serology test for hepatitis C, and a frequency of
4.42% (n = 70) of...

Strategies to reduce mortality and morbidity due to AIDS-related cryptococcal meningitis in Latin
America
Provedor de dados: 55
Autores: Vidal,Jose E.; Oliveira,Augusto C. Penalva de; Dauar,Rafi F.; Boulware,David R.
Latin America is the region with the third most AIDS-related cryptococcal meningitis infections globally. Highly active
antiretroviral therapy (HAART) has reduced the number of infections; however, the number of deaths and the case-fatality rate
continues to be unacceptable. In this review, we focus on the burden of AIDS-related cryptococcosis in Latin America and discuss
potential strategies to reduce early mortality from Cryptococcus. In this review, we highlight the importance of: (1) earlier HIV
diagnosis and HAART initiation with retention-in-care to avoid AIDS; (2) pre-HAART cryptococcal antigen (CRAG) screening
with preemptive fluconazole treatment; (3) better diagnostics (e.g. CRAG testing); and (4) optimal treatment with aggressive
management of...

The need for timely collection and analysis of epidemiological data is becoming of primary importance, e.g., for bioterrorism
detection or epidemiological surveillance. Web-based information systems (WISs) may provide the needed technological support.
Thus we present the WeeW (workflow-enabled epidemiological WIS) system—i.e., a WIS that helps epidemiologists, through
workflow management, to effectively select remote centers, collect, and process the received data to produce conclusive technical
reports. In detail, we show the functionalities of the WeeW system, its architecture, and particularly Stata’s role in executing
statistical analyses and producing graphs. Furthermore, we discuss the performance of the WeeW–Stata interface. Finally, we

A PCR-based survey of hemoprotozoa parasites detected Babesia bigemina, Theileria orientalis and Trypanosoma theileri among
cattle and water buffalo in Vietnam, and a new Babesia sp. closely related to Babesia ovata was detected in cattle only. In
addition, Theileria annulata and Trypanosoma evansi were not detected in both cattle and water buffalo. Phylogenetic analysis
detected T. orientalis MPSP genotypes 3, 5, 7 and N3 in cattle and 5, 7, N1 and N2 in water buffalo. Additionally, water
buffalo-derived T. theileri CATL sequences clustered together with a previously reported cattle-derived sequence from Vietnam.
This is the first report of a new Babesia sp. in cattle, and T. orientalis MPSP genotype 7 and T. theileri in water buffalo in
Vietnam.

Provedor de dados: 102
Autores: Willocquet,Laetitia; Allorent,Delphine; Savary,Serge.
This work quantifies two important epidemiological features of the bean (Phaseolus vulgaris)/Phaeoisariopsis griseola
pathosystem. The first is the effect of the number of nights of leaf wetness on infection efficiency. Infection efficiency was below
10% when inoculated leaflets were exposed to less than two nights of leaf wetness. Optimum infection efficiencies were obtained
after three to four nights of leaf wetness, at about 50%. Further nights of leaf wetness did not increase the infection efficiency. The
second feature quantified is the relative rate of leaflet defoliation for varying levels of angular leaf spot severity. It increased with
disease severity according to a logarithm-like curve, and a relative rate of 0.23 day-1 was estimated for a...

Producer Livestock Disease Management Incentives and Decisions
Provedor de dados: 31
Autores: Wolf,
Christopher A.
This paper examines the economics of farm decisions to prevent and control infectious livestock disease. In the case of diseases
with costly control tolerating some level of disease is often rational to the producer. Public policy intervention is based on future
value and public good aspects of disease control which can lead to a discrepancy between private and public action thresholds.
Producer incentives for disease management can be changed through new technologies that lower the cost of prevention or
control, subsidies or cost sharing of control measures, or on the consumer side, a change in public desire for disease risk-free
products that changes relative prices. Economists can incorporate appropriate epidemiology of a given disease in economic...

Autores: Xie,
Fang; Horan,
Richard D.
This paper investigates private responses and ecological impacts of policies proposed to confront the problem of brucellosis being
spread from elk to cattle in Wyoming. The policies consist of combinations of changes in elk feeding and population levels.
Farmers' responses to these dynamics are modeled along with the associated impacts to livestock population dynamics. Our
findings suggest that feedbacks between jointly determined disease dynamics and decentralized economic behavior matter, and the
elk feedgrounds do not actually generate economic harm to the individual farmers.

Richard D.
Brucellosis is a highly infectious bacterial disease that causes infected females to abort their calves. It has caused devastating
losses to U.S. farmers over the last century. The only known focus of Brucellosis left in the nation is wildlife such as bison and elk
in the Greater Yellowstone Area. Vaccination and test-and-slaughter have been applied to brucellosis management in bison, and
there has been discussion that a combination of both could potentially eradicate the disease in the Yellowstone National Park.
However, there is no study on how to allocate resources between the two actions. This paper investigates the optimal allocation of
these two selective management options, in a bioeconomic framework, when there are both existence and recreational...

This study evaluated the epidemiological behavior of the hepatitis A in Paraná state and compared the costs of the disease and the
vaccination. This is an epidemiological descriptive study including a pharmacoeconomy analysis. We collected information in the
national database reported cases (SINAN), in the mortality information system (SIM) and in the hospital information system
(AIH) among 2000/2003 (Paraná State Public Health Department). We estimated the probability of one cohort of children to
acquire hepatitis A during their lifetime and the costs with their treatment. We compared those costs with the cost of vaccinating
the children. 14,682 hepatitis A cases were registered during the period studied, and 12,102 (82.4%) occurred in the 0-15
