Abstract:
From January, 1984 to March, 1999, 31 children under 15 y old (ages 1-14 y, median 8 y) were admitted after being bitten by rattlesnakes (Crotalus durissus ssp). One patient was classified as "dry-bite", 3 as mild envenoming, 9 as moderate envenoming and 18 as severe envenoming. Most patients had neuromuscular manifestations, such as palpebral ptosis (27/31), myalgia (23/31) and weakness (20/31). Laboratory tests suggesting rhabdomyolysis included an increase in total blood creatine kinase (CK, 28/29) and lactate dehydrogenase (LDH, 25/25) levels and myoglobinuria (14/15).

Abstract:
Thirty-two patients bitten by venomous snakes sixteen by Bothrops spp. and sixteen by Crotalus durissus terrificus were studied. The group comprised thirty males and two females, aged eight to sixty-three years (mean 33±15). Bromsulphalein tests were increased in the majority of patients bitten by Crotalus durissus terrificus. The correlation coefficient of Spearman was positive between bromsulphalein tests and alanine aminotransferase levels, and between alanine aminotransferase and aspartate aminotransferase levels only in the Crotalus group. The only patient who died was bitten by Crotalus

Abstract:
Chronic wounds are a major health problem that cause millions of dollars in expenses every year. Among all the treatments used, active wound treatments such as enzymatic treatments represent a cheaper and specific option with a fast growth category in the market. In particular, bacterial and plant proteases have been employed due to their homology to human proteases, which drive the normal wound healing process. However, the use of these proteases has demonstrated results with low reproducibility. Therefore, alternative sources of proteases such as snake venom have been proposed. Here, we perf

Abstract:
The goal of this study was to determine the prevalence of Hepatozoon spp. infection in recently captured snakes from Botucatu, São Paulo State, Brazil. Blood was collected from all snakes by ventral tail venipuncture. Blood smears were air dried, fixed with methanol, and stained with 10% Giemsa solution. The slides were microscopically examined for detection of hemoparasites by light microscopy at 250x magnification. A total of 238 snakes from 23 species were examined, of which 135 (56.7%) were venomous and 103 (43.3%) non-venomous snakes. The more numerous venomous species sampled were Crotal

A revisão da literatura pertinente indica que as opiniões sobre a importância dos acidentes ofídicos, como causa de mortes em bovinos no Brasil, são divergentes no meio veterinário. Enquanto alguns acreditam que são pouco importantes, ou que têm menor significado do que lhes é atribuído, outros são da opinião que esses acidentes são freqüentes. Verificou-se que só foi relatado diagnóstico fundamentado de dois casos fatais de envenenamento por Bothrops spp em bovinos, e de nenhum por Crotalus spp. Um questionário por nós submetido a patologistas e clínicos veterinários que atuam em diversos Est

Abstract:
Mexico is home to a large number of reptile species and has one of the greatest diversities of venomous snakes, among which the rattlesnakes pertaining to the Crotalus genus stand out. Out of more than 40 species in the country, nine are found in Zacatecas: C. aquilus, C. atrox, C. basiliscus, C. lepidus, C. molossus, C. polystictus, C. pricei, C. scutulatus and C. willardi. Although these reptiles are important, due to their relevance in terms of ecology, cultural use and public health, their conservation is impacted by multiple factors, such as habitat fragmentation and indiscriminate killin

Abstract:
Every year large numbers of rattlesnakes (Crotalus spp. and Sistrurus spp.) are collected from the wild in several states in North America. Some of these are collected purely for commercial reasons while others are collected for the traditional, although now largely commercial, ‘rattlesnake round-ups’. Together these activities may remove 300,000–500,000 snakes each year. The high level of hunting together with capture procedures that destroy habitat as well as snakes are damaging rattlesnake populations, other species, and habitat quality.

Abstract:
ABSTRACTMovements of ectotherms are constrained by their body temperature owing to the effects of temperature on muscle physiology. As physical performance often affects the outcome of predator–prey interactions, environmental temperature can influence the ability of ectotherms to capture prey and/or defend themselves against predators. However, previous research on the kinematics of ectotherms suggests that some species may use elastic storage mechanisms when attacking or defending, thereby mitigating the effects of sub-optimal temperature. Rattlesnakes (Crotalus spp.) are a speciose group of
