Snake venomics of Bothriechis nigroviridis reveals extreme variability among palm pitviper venoms: different evolutionary solutions for the same trophic purpose
We report the proteomic characterization and biological activities of the venom of the black-speckled palm pitviper, Bothriechis nigroviridis, a neotropical arboreal pitviper from Costa Rica. In marked contrast to other ...
Antivenomics of Atropoides mexicanus and Atropoides picadoi snake venoms: Relationship to the neutralization of toxic and enzymatic activities
Viperid snakes of the genus Atropoides are distributed in Mexico and Central America and, owing to their size and venom yield, are capable of provoking severe envenomings in humans. This study evaluated, using an ‘antivenomics’ ...
Isolation of an acidic phospholipase A2 from the venom of the snake Bothrops asper of Costa Rica: Biochemical and toxicological characterization
Phospholipases A2 (PLA2) are major components of snake venoms, exerting a variety of relevant toxic actions such as neurotoxicity and myotoxicity, among others. Since the majority of toxic PLA2s are basic proteins, acidic ...
Snake Venomics and Antivenomics of the Arboreal Neotropical Pitvipers Bothriechis lateralis and Bothriechis schlegelii
We report the comparative proteomic characterization of the venoms of two related neotropical arboreal pitvipers from Costa Rica of the genus Bothriechis, B. lateralis (side-striped palm pit viper) and B. schlegelii (eyelash ...
Snake Venomics of the Lesser Antillean Pit Vipers Bothrops caribbaeus and Bothrops lanceolatus: Correlation with Toxicological Activities and Immunoreactivity of a Heterologous Antivenom
The venom proteomes of the snakes Bothrops caribbaeus and Bothrops lanceolatus, endemic to the Lesser Antillean islands of Saint Lucia and Martinique, respectively, were characterized by reversephase HPLC fractionation, ...
Venomic and antivenomic analyses of the Central American coral snake, Micrurus nigrocinctus (Elapidae)
The proteome of the venom of Micrurus nigrocinctus (Central American coral snake) was analyzed by a “venomics” approach. Nearly 50 venom peaks were resolved by RP-HPLC, revealing a complex protein composition. Comparative ...
