Autores: Catroxo,M. H. B; Martins,A. M. C. P. F; Petrella,S; Milanelo,L; Aschar,M; Souza,F; Nastari,B.D.B; Souza,R.B.
Diseases caused by avian paramyxovirus (APMV) occur in commercial, captive and wild birds worldwide, demonstrating the
significant economic and ecological importance of these agents. Paramyxoviruses belong to the Paramyxoviridae family,
Paramyxovirinae subfamily and Avulavirus genus. During the period 2000 to 2011, stool and small intestine samples of 1647
birds species were sent to the Laboratory of Electron Microscopy, Biological Institute of São Paulo, Brazil, for diagnosis of viral
agents. The samples were processed by negative staining (rapid preparation) and resin embedding techniques. Under the
transmission electron microscope by negative staining technique, in 294 (17.8%) samples of 1647 were visualized paramyxovirus
particles pleomorphic, roughly...

Botulism in non-ruminants in Brazil
Provedor de dados: 65
Autores: Oliveira Júnior,Carlos Augusto de; Silva,Rodrigo Otávio Silveira; Olinda,Roberio Gomes; Lobato,Francisco Carlos
Faria.
ABSTRACT: Botulism is an intoxication caused by the ingestion of neurotoxins secreted by Clostridium botulinum and
characterized by progressive flaccid symmetrical paralysis. Among non-ruminant animals, avian species and dogs are the most
commonly affected by botulism, while horses and pigs are less-commonly diagnosed with the disease. Despite the importance of
this disease in animals, the Brazilian literature only includes case studies and outbreak descriptions. The aim of this study was to
review the main features and to provide recent data on the occurrence of botulism in non-ruminants in Brazil.

Comparative Quantitative and Qualitative Attributes of the Surface Respiratory Macrophages in the
Domestic Duck and the Rabbit
Provedor de dados: 77
Autores: Mutua,P. M; Gicheru,M. M; Makanya,A. N; Kiama,S. G.
In mammals, surface respiratory macrophages (SM) are known to play a foremost role in protecting the respiratory system by
providing first line of defense through engulfing pathogens and particulate matter respired with air. It has been reported that the
pulmonary cellular defense system of domestic birds is inadequate. In particular, low number of SM and even lack of the cells in a
healthy avian respiratory system have been associated with susceptibility of domestic birds to respiratory diseases. In an endeavor
to resolve the existing controversy, the quantitative and qualitative attributes of the surface respiratory macrophages of the
domestic duck and of the domestic rabbit were compared under similar experimental conditions. Quantitatively, the rabbit...

Genotyping and antimicrobial susceptibility of Clostridium perfringens isolated from Tinamidae,
Cracidae and Ramphastidae species in Brazil
Provedor de dados: 65
Autores: Silva,Rodrigo Otávio Silveira; Ferreira Junior,Francisco Carlos; Marques,Marcus Vinícius Romero; Oliveira
Junior,Carlos Augusto; Martins,Nelson Rodrigo da Silva; Lobato,Francisco Carlos Faria.
The aim of this study was to isolate, genotype and evaluate the antimicrobial susceptibility of Clostridium perfringens found in
species Tinamidae, Cracidae and Ramphastidae in Brazil. C. perfringens was isolated in 13 (5%) out of 260 swab samples and
five (8.3%) out of 60 stool samples. All strains were classified as C. perfringens type A, and nine (50%) were positive for the
beta-2 toxin-encoding gene. No strains were positive for the necrotic enteritis toxin B-like (NetB)-encoding gene. All isolates
were susceptible to penicillin, metronidazole and vancomycin, whereas four (22.2%), five (27.8%) and 13 (72.2%) strains were
considered resistant to erythromycin, oxytetracycline and lincomycin, respectively.

Hematologic reference values of Vinaceous-breasted Amazon (Amazona vinacea)

ABSTRACT Avian hematologic reference intervals are useful tools to evaluate body homeostasis and diagnose diseases.
However, there are few species-specific reference intervals published. The present study reports Vinaceous-breasted Amazon (
Amazona vinacea ) hematologic reference values obtained during the health status evaluation of release candidates as part of this
species reintroduction efforts at the Araucárias National Park. Parameters reported are erythrogram (erythrocytes, hemoglobin,
packed cell volume, mean cell volume, mean corpuscular hemoglobin concentration and mean corpuscular hemoglobin), Red Cell
Distribution Width (RDW), white cells total and differential (heterophiles, lymphocytes, basophils, eosinophils and monocytes),
thrombocytes and...

MORPHO-CYTOCHEMICAL AND ULTRASTRUCTURAL CHARACYERIZATION OF
PERIPERAL THROMBOCYTES OF ROADSIDE HAWK Buteo magnirostris GMELIN, 1788)
(AVIAN, FALCONIFORM)
Provedor de dados: 77
Autores: Aguiar Santos,Antenor; Marques Joppert da Silva,Adriana; Lima de Carvalho,Vinicius Antonio; Imoto Egami,Mizue.
Basic hematological information about the avian in its natural habitat is limited. In this study we aimed at investigating, in the
peripherical blood of the roadside hawk, Buteo magnirostris, the number of thrombocytes and their morphological, cytochemical
and ultrastructural aspects. Blood smears were submited to the following methods: Leishman for morphological analysis and
specific methods for the characterization of four kinds of macromolecules of different chemical nature: Glycogen, lysosomal
enzymes (myeloperoxidase and the acid phosphatase), basic polyaminoacid rich proteins and phospholipids. The average number
of thrombocytes was 26.8 x 10³ ± 10,2 / µL. Structurally the thrombocytes present predominantly elliptic
shape, with...

Oology and the evolution of thermophysiology in saurischian dinosaurs: homeotherm and endotherm
deinonychosaurians?
Provedor de dados: 84
Autores: Grellet-Tinner,Gerald.
The origin of avian endothermy is a long-held question the answer of which cannot be provided by first level observations.
Oological and reproductive characters have collectively provided a new source of data useful for phylogenetic analyses and
paleobiological inferences. In addition, the observations of reproductive and oological evolutionary trends in saurischian dinosaurs
lead to the interpretation that not only, the thermophysiology of these dinosaurs progressively became more avian-like but after
re-examination allows to infer that deinonychosaurians represented here by three troodontids and one dromaeosaurid might
already have developed an avian-like endothermy, thus predating the rise of avians. These results based on reproductive traits
are...
