Preclinical assessment of a polyspecific antivenom against the venoms of Cerrophidion sasai, Porthidium nasutum and Porthidium ophryomegas: Insights from combined antivenomics and neutralization assays
(2013-03-15)
A polyspecific antivenom is used in Central America for the treatment of envenomings by viperid snakes. This antivenom is generated in horses hyperimmunized with a mixture of venoms from Bothrops asper, Crotalus simus and ...
Snake population venomics and antivenomics of Bothrops atrox: Paedomorphism along its transamazonian dispersal and implications of geographic venom variability on snakebite management
(2011-04-11)
We describe two geographically differentiated venom phenotypes across the wide distribution range of Bothrops atrox, from the Colombian Magdalena Medio Valley through Puerto Ayacucho and El Paují, in the Venezuelan States ...
Isolation of an acidic phospholipase A2 from the venom of the snake Bothrops asper of Costa Rica: Biochemical and toxicological characterization
(2010-03)
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 Bothrops atrox venoms from Colombia and the Amazon regions of Brazil, Perú and Ecuador suggest the occurrence of geographic variation of venom phenotype by a trend towards paedomorphism
(2009-11-02)
The venom proteomes of Bothrops atrox from Colombia, Brazil, Ecuador, and Perú were characterized using venomic and antivenomic strategies. Our results evidence the existence of two geographically differentiated venom ...
Snake venomics of Bothriechis nigroviridis reveals extreme variability among palm pitviper venoms: different evolutionary solutions for the same trophic purpose
(2010)
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 ...
Assessing the preclinical efficacy of antivenoms: From the lethality neutralization assay to antivenomics
(2013-07)
The assessment of the capacity of antivenoms to neutralize the lethal activity of snake
venoms is the gold standard in the preclinical analysis of antivenom efficacy, and is
routinely performed by manufacturers and quality ...
Venoms of Micrurus coral snakes: evolutionary trends in compositional patterns emerging from proteomic analyses
(2016-11)
The application of proteomic tools to the study of snake venoms has led to an impressive growth in the
knowledge about their composition (venomics), immunogenicity (antivenomics), and toxicity (toxicovenomics).
About ...
A novel pentameric phospholipase A2 myotoxin (PophPLA2) from the venom of the pit viper Porthidium ophryomegas
(2018-06-07)
The first toxin isolated from the venomous pit viper Porthidiumophryomegas is a basic pentameric phospholipase
A2 (PophPLA2). Elucidation of its amino acid sequence showed that it belongs to the group IIA of secreted ...
Antivenomics: a proteomics tool for studying the immunoreactivity of antivenoms
(2015-03)
Envenoming following snakebite is largely a neglected threat to public health in tropical and subtropical regions of Africa, Asia, Latin America and Oceania addicting some of the world’s poorest rural communities. An ...
Snake Venomics and Antivenomics of the Arboreal Neotropical Pitvipers Bothriechis lateralis and Bothriechis schlegelii
(2008-04-30)
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 ...
