Renal failure and neonatal death following snakebite during pregnancy: a case report
Provedor de dados: 80
Autores: Adam,G. K.; Hussein,S. M.; Adam,I.
A thirty-five-year-old Sudanese woman (gravida 4, para 3), at 34 weeks gestational age, presented with snakebite in her right leg.
Examination of the cardiovascular, respiratory, gastrointestinal, and central nervous systems revealed no abnormalities. Her blood
urea was 58 mg/dl; creatinine, 2.6 mg/dl; whole blood clotting time, 5:35 minutes. The patient was diagnosed as having acute
renal failure and was then managed conservatively. She received polyvalent antivenom serum intravenously. On the next day, she
delivered prematurely and the baby passed away due to respiratory distress. There was no postpartum bleeding and the patient's
clotting time was 5:30 minutes. She was discharged from the hospital after 7 days when her clinical, biochemical and...

Feeding ecology of Liophis reginae semilineatus (Serpentes: Colubridae: Xenodontinae) in eastern
Amazon, Brazil
Provedor de dados: 103
Autores: Albarelli,Luiz Paulo P.; Santos-Costa,Maria C.
We studied the diet of Liophis reginae semilineatus (Wagler, 1824) from eastern Amazon, Brazil, based on the analysis of 182
preserved specimens. Thirty-six individuals had prey in their stomachs; 34 (95%) contained exclusively anurans and 2 (5%)
contained both anurans and lizards. The most common prey items were small Leptodactylus sp. (33.3%), followed by
Physalaemus ephippifer (Steindachner, 1864) (10.3%). Prey ingested head-first (78%; n = 25) were significantly larger than prey
ingested tail-first (22%; n = 7). Females of L. reginae semilineatus have longer and wider heads than conspecific males with the
same body length, which correspond to sexual divergences in the diet (size of the prey). No correlation was found between snake
head length vs. prey...

Records of the rattlesnakes Crotalus durissus terrificus (Laurenti) (Serpentes, Viperidae) in the State
of Rio de Janeiro, Brazil: a possible case of invasion facilitated by deforestation
Provedor de dados: 104
Autores: Bastos,Eduardo G. de M.; Araújo,Alexandre F. B. de; Silva,Hélio R. da.
This paper documents the presence of rattlesnakes, as an invasive species, in several municipalities of the State of Rio de Janeiro.
As previous registers indicate, these snakes probably invaded at least the municipality of Valença carried by floodwaters between
the decades of 1950 and 1960. In the new environment, along the margins of the Rio Preto, these snakes were able to establish
new populations in deforested areas turned into cattle grazing. The presence of rattlesnake in the municipality of Barra do Piraí, a
municipality that has no border with Rio Preto, however, indicates that these snakes dispersal into new areas may be facilitated by
open areas, represented by pastures, created after deforestations.

Paths to the discovery of antivenom serotherapy in France
Provedor de dados: 80
Autores: Bochner,Rosany.
Abstract The current study presents a descriptive chronological survey of the articles published by Césaire Auguste Phisalix and
Albert Calmette on snake poison, with the aim of shedding a light on the areas of research and reasoning followed by these
scientists, leading up to their simultaneous discovery of antivenom serotherapy in 1894. The path taken by Phisalix is revealed in
15 articles that demonstrate the motivation of a naturalist and the way he confronted the puzzle of immunity against snake venom.
In the case of Calmette, two articles preceded the discovery; microbiology was his theoretical base and the Pasteurian spirit of
solving health problems his driving force. These two researchers followed distinct paths, mobilized by different...

Does gestation or feeding affect the body temperature of the golden lancehead, Bothrops insularis
(Squamata: Viperidae) under field conditions?
Provedor de dados: 103
Autores: Bovo,Rafael P.; Marques,Otavio A. V.; Andrade,Denis V.
Temperature affects physiological performance in reptiles and, therefore, body temperature (Tb) control is argued to have an
important adaptive value. Alterations in Tb due to transient changes in physiological state, as during digestion or gestation, are
often linked to the potential benefits of a more precise Tb regulation. However, such thermoregulatory responses in nature remain
controversial, particularly for tropical snakes. Herein, we measured Tb of the golden lanceheads, Bothrops insularis (Amaral,
1921), at Queimada Grande Island, southeastern Brazil, to test for alteration in selected body temperatures associated with feeding
or gestation. We found no evidence that postprandial or gravid snakes selected for higher Tb indicating that, under...

Polychromatism of populations of Corallus hortulanus (Squamata: Boidae) from the southern
Amazon Basin, Brazil
Provedor de dados: 36
Autores: DUARTE,Mel de Oliveira; FREITAS,Tiago Magalhães da Silva; PRUDENTE,Ana Lúcia da Costa.
The Amazon tree boa Corallus hortulanus is known for featuring a wide variation in color pattern and design markings. Although
there are studies on its polychromatism, none of them addresses the geographic variation in the color pattern of this species. The
aim of this study was to describe the chromatic variation found in the populations of C. hortulanus from the southern Amazon
Basin and its relationship with geographic distribution of the species. Analysis of both design markings and color patterns on 112
C. hortulanus specimens from the southern Amazon Basin interfluves resulted in the identification of six distinct morphotypes.
Grayish-brown coloration and elongated diamond-shaped patterns were the most frequent patterns. Two morphotypes showed a...

The presence of pharmacological substances myoglobin and histamine in venoms
Provedor de dados: 79
Autores: LIPPS,B. V.; KHAN,A. A.
It is well documented that several pharmacological substances are released within the victim's body after snakebite. These
substances are also believed to be endogenously present in animals, specifically levels of myoglobin and histamine that are
reported to rise after envenomation. However, there is no published data regarding the presence of these substances in venoms per
se. This research reports the detection of myoglobin and histamine in snake, scorpion, honeybee, and toad venoms by
immunological test. It is unlikely that the rise in levels of myoglobin and histamine is due to that added from the bite, since a
single toxin devoid of such components is capable of elevating levels of these substances. Nonetheless, it is likely that the rise in
levels of...

Background : Hematology and plasma biochemistry parameters are useful in the assessment and management of snake
physiological status. Although reference ranges are readily available for many snake species, they are lacking for most venomous
ophidians. We determined hematology and plasma biochemistry reference ranges for the wild-caught Indian cobra, Naja
naja.Results : Blood samples, taken from the ventral tail vein, were assessed for erythrocyte count, total leukocyte count,
hemoglobin concentration, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular
hemoglobin concentration, considering the sex of snakes. Results revealed the erythrocyte numbers (male, 390000 ±
12503.33/mm3 and female, 347500 ± 7505.55/mm3), shapes and...

snake venom from Chiriguaná (Cesar, Colombia)
Provedor de dados: 80
Autores: Ramírez-Avila,J.; Quevedo,B. E.; López,E.; Renjifo,J. M.
Components with phospholipase A2 activity were isolated by gel filtration and cationic exchange chromatography from the
venom of Bothrops asper snakes from Chiriguaná, Colombia (9°22´N; 73°37´W).
Five fractions were obtained by the gel filtration, and PLA2 activity was found in fraction 3 (F3). In the cationic exchange
chromatography, F3 showed eight components with PLA2 activity. Six of these components appeared as one band in
polyacrylamide gel electrophoresis (SDS-PAGE). Fractions II and VII exhibited an optimal activity at pH 9 and 52ºC.
The optimum calcium concentration for fraction II was 48 mM and for fraction VII, 384 mM. Both fractions showed thermal
stability. Fraction II was stable at pH values...

The occurrence of Crepidobothrium sp.(Cestoda, Proteocephalidae) in the intestine of Bothrops moojeni (Hoge,1965)(Serpentes,
Viperidae) is reported. The host snake was rescued from the fauna in Porto Primavera dam, Mato Grosso do Sul State, Brazil. The
snake died in captivity on July 13,1999. At necropsy, 28 tapeworms were found in the snake intestine. The analysis of specimens
morphology allowed the conclusion that they belong to the Crepidobothrium (Monticelli, 1900) genus. It was not possible to
determine the Crepidobothrium species due to the lack of the gravid proglottids. This is the first report of B. moojeni as a host of
cestodes.

Defensive repertoire of Xenodon dorbignyi (Serpentes, Dipsadidae)
Provedor de dados: 49
Autores: Tozetti,Alexandro Marques; Oliveira,Roberto Baptista de; Pontes,Glaucia Maria Funk.
The ability of a species to defend itself against a predator is directly correlated with its survivorship. Thus, prey/predator
interaction mechanisms are important elements of the natural history of species. In this study, we examined the defensive
repertoire of the South-American hognose snake (Xenodon dorbignyi) through simulations of predator attacks in the field. Nine
defensive displays were observed. The most frequently observed displays were erratic movements, body flattening, head
triangulation and tail display. No differences were detected in the defensive strategies shown by males and females, regardless of
their reproductive state. Our findings suggest that X. dorbignyi has the ability to evaluate the level of threat imposed by the
aggressor,...
