13. Envenomation by an opisthoglyphous snake, Erythrolamprus aesculapii (Dipsadidae), in southeastern Brazil
Abstract Snakebites by aglyphous or opisthoglyphous snakes are common in Brazil. We report a case of snakebite by the opisthoglyphous Erythrolamprus aesculapii. The victim presented with pain, edema, and bleeding at the bite site, along with erythema, similar to a Bothrops envenomation. In this type of snakebite, if the snake is not brought to the hospital,

14. Reproductive and feeding biology of the common lancehead Bothrops atrox (Serpentes, Viperidae) from central and southwestern Brazilian Amazonia
RESUMO A jararaca Bothrops atrox é uma serpente de ampla distribuição e de importância médica na Amazônia. Visto que a biologia reprodutiva e alimentar de serpentes varia geograficamente, nosso objetivo foi o de caracterizar a história natural de indivíduos provenientes das porções central e sudoeste do bioma no Brasil. Analisamos espécimes preser

15. Composition and ecology of a snake assemblage in an upland forest from Central Amazonia
Abstract: Most species of Amazonian snakes have wide geographic distributions. However, local environmental factors influence the formation of assemblages in different localities. In this study, we investigated the composition of the assemblage and the effect of environmental variables on the distribution of the species inhabiting an upland forest in the Exp

16. Subproteome of Lachesis muta rhombeata venom and preliminary studies on LmrSP-4, a novel snake venom serine proteinase
Abstract Background: Lachesis muta rhombeata is one of the venomous snakes of medical importance in Brazil whose envenoming is characterized by local and systemic effects which may produce even shock and death. Its venom is mainly comprised of serine and metalloproteinases, phospholipases A2 and bradykinin-potentiating peptides. Based on a previously report

17. A case of envenomation caused by Oxybelis fulgidus (Serpentes, Colubridae) in Brazilian Amazon
Abstract A case of a bite inflicted by Oxybelis fulgidus in the wilds of Amazon is reported. The patient was a 67-year-old man who presented with dizziness, tachycardia and local pain, with erythema and bleeding in his left arm. The venom of Oxybelis fulgidus, a neotropical rear-fanged snake, contains one of the four three-finger toxins already isolated from

18. Aspects of reproduction and sexual dimorphism of Lygophis flavifrenatus (Dipsadidae: Xenodontinae)
RESUMO Lygophis flavifrenatus Cope, 1862 é um dipsadídeo terrestre distribuído pelo Brasil subtropical, Paraguai, Uruguai e Argentina. Apresentamos aqui dados sobre dimorfismo sexual e biologia reprodutiva desta espécie muito pouca estudada. Um total de 108 espécimes (55 fêmeas, 50 machos, três filhotes com sexo não identificado) procedentes dos esta

19. Next-generation sequencing analysis reveals high bacterial diversity in wild venomous and non-venomous snakes from India
Abstract Background: The oral cavities of snakes are replete with various types of bacterial flora. Culture-dependent studies suggest that some of the bacterial species are responsible for secondary bacterial infection associated with snakebite. A complete profile of the ophidian oral bacterial community has been unreported until now. Therefore, in the pres

20. Kn-Ba: a novel serine protease isolated from Bitis arietans snake venom with fibrinogenolytic and kinin-releasing activities
Abstract Background: Bitis arietans is a venomous snake found in sub-Saharan Africa and in parts of Morocco and Saudi Arabia. The envenomation is characterized by local and systemic reactions including pain, blistering, edema and tissue damage, besides hemostatic and cardiovascular disturbances, which can cause death or permanent disabilities in its victims

21. Clinical and laboratory features distinguishing between Deinagkistrodon acutus and Daboia siamensis envenomation
Abstract Background: There are 6 species of venomous snakes in Taiwan. Two of them, Deinagkistrodon acutus (D. acutus) and Daboia siamensis (D. siamensis), can cause significant coagulopathy. However, a significant proportion of patients with snakebites cannot identify the correct snake species after envenomation, which hampers the application of antivenom.

22. Popular names for bushmaster (Lachesis muta) and lancehead (Bothrops atrox) snakes in the Alto Juruá region: repercussions for clinical-epidemiological diagnosis and surveillance
Abstract INTRODUCTION: The popular names “surucucu” and “jararaca” have been used in literature for Lachesis muta and Bothrops atrox snakes, respectively. We present the popular names reported by patients who suffered snakebites in the Alto Juruá region. METHODS: Fifty-seven (76%) patients saw the snakes that caused the envenomations and were as

23. The Herpetofauna from Ilha Grande (Angra dos Reis, Rio de Janeiro, Brazil): updating species composition, richness, distribution and endemisms
Abstract Ilha Grande is a large continental island (total area of 19,300 ha) situated at the southern coast of the state of Rio de Janeiro, in southeast Brazil, within the Atlantic Forest Biome. Here we provide an update to the previous knowledge of the fauna of amphibians and reptiles occurring in Ilha Grande, based on primary data from our own fieldwork an

24. A new species of burrowing snake (Serpentes: Dipsadidae: Apostolepis ) from the state of Mato Grosso, Central-West region of Brazil
ABSTRACT During a faunal rescue conducted at a hydroelectric power station constructed in a Cerrado savanna area in the state of Mato Grosso, a sample of five small stripe-patterned individuals of snakes of the genus Apostolepis Cope, 1862 document the existence of an undescribed species, which is named herein. The new species can be distinguished from its c
