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 ...
Isolation and characterization of four medium-size disintegrins from the venoms of Central American viperid snakes of the genera Atropoides, Bothrops, Cerrophidion and Crotalus
(2014-12)
Four disintegrins were isolated from the venoms of the Central American viperid snakes Atropoides mexicanus (atropoimin), Bothrops asper (bothrasperin), Cerrophidion sasai (sasaimin), and Crotalus simus (simusmin). ...
Preclinical efficacy of Australian antivenoms against the venom of the small-eyed snake, Micropechis ikaheka, from Papua New Guinea: An antivenomics and neutralization study
(2014-10-14)
There is no specific antivenom for the treatment of envenoming by the small-eyed snake, Micropechis ikaheka, a dangerous fossorial species endemic to Papua New Guinea, Irian Jaya (West Papua) and neighbouring islands. This ...
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).

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 ...
Comparative study of the cytolytic activity of snake venoms from African spitting cobras (Naja spp., Elapidae) and its neutralization by a polyspecific antivenom
(2011-11)
Venoms of several Naja species found in Sub-Saharan Africa, and commonly known as "spitting cobras", induce a predominantly cytotoxic pattern of envenomings that may evolve into tissue necrosis and gangrene. Cytotoxic ...
Preclinical assessment of the efficacy of a new antivenom (EchiTAb-Plus-ICP) for the treatment of viper envenoming in sub-Saharan Africa
(2010-02)
A preclinical assessment was performed on the neutralizing efficacy of a whole IgG polyspecific antivenom (EchiTAb-Plus-ICP®), designed for the treatment of snakebite envenomings in Nigeria. It was generated by immunizing ...
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 ...
Evaluation of the preclinical efficacy of four antivenoms, distributed in sub-Saharan Africa, to neutralize the venom of the carpet viper, Echis ocellatus, from Mali, Cameroon, and Nigeria
(2015-11)
Snakebite envenoming causes a heavy toll in sub-Saharan Africa in terms of mortality and sequelae. In the West African savannah, the viperid Echis ocellatus is responsible for the vast majority of bites. In the last decades, ...
