Isolation and Functional Characterization of an Acidic Myotoxic Phospholipase A2 from Colombian Bothrops asper Venom [PDF]
Toxins, 2017 Myotoxic phospholipases A2 (PLA2) are responsible for many clinical manifestations in envenomation by Bothrops snakes. A new myotoxic acidic Asp49 PLA2 (BaCol PLA2) was isolated from Colombian Bothrops asper venom using reverse-phase high performance ...

Computational Modeling of Low-Abundance Proteins in Venom Gland Transcriptomes: Bothrops asper and Bothrops jararaca [PDF]
ToxinsSnake venoms contain numerous toxic proteins, but low-abundance proteins often remain uncharacterized due to identification challenges. This study employs a bioinformatics approach to identify and structurally model low-abundance proteins from the venom ...

Exploring the Venom Gland Transcriptome of Bothrops asper and Bothrops jararaca: De Novo Assembly and Analysis of Novel Toxic Proteins [PDF]
ToxinsPrevious proteomic studies of viperid venom revealed that it is mainly composed of metalloproteinases (SVMPs), serine proteinases (SVSPs), phospholipase A2 (PLA2), and C-type lectins (CTLs).

Pan-American Lancehead Pit-Vipers: Coagulotoxic Venom Effects and Antivenom Neutralisation of Bothrops asper and B. atrox Geographical Variants [PDF]
Toxins, 2021 The toxin composition of snake venoms and, thus, their functional activity, can vary between and within species. Intraspecific venom variation across a species’ geographic range is a major concern for antivenom treatment of envenomations, particularly ...

Feeding ecology of the Terciopelo pit viper snake (Bothrops asper) in Ecuador. [PDF]
PeerJ, 2023 Thoroughly documenting prey items and diet composition is crucial for understanding a predator’s role in the ecosystem. In gape restricted predators, such as snakes, documenting and analyzing the type and size of the prey is important to interpret their ecological role.

Differences in plasmatic butyrylcholinesterases (BChE) values between Pacific and Caribbean populations of terciopelo (Bothrops asper) in Costa Rica [PDF]
Heliyon, 2019 The terciopelo (Bothrops asper) inhabits human-modified environments such as agricultural areas, becoming more prone to be exposed to organophosphate insecticides. These chemicals can inhibit plasmatic butyrylcholinesterases (BChE) activity in B.
