Venom, venomics, antivenomics
(2009)
Venoms comprise mixtures of peptides and proteins tailored by Natural Selection to act on vital systems
of the prey or victim. Here we review our proteomic protocols for uncoiling the composition,
immunological profile, ...
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 ...
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). ...
Snake venomics and antivenomics: Proteomic tools in the design and control of antivenoms for the treatment of snakebite envenoming
(2009-03-06)
Snakebite envenoming represents a neglected tropical disease that has a heavy public health impact, particularly in Asia, Africa and Latin America. A global initiative, aimed at increasing antivenom production and ...
Snake venomics and toxicological profiling of the arboreal pitviper Bothriechis supraciliaris from Costa Rica
(2012-04)
The genus Bothriechis comprises a lineage of nine species of Neotropical pitvipers distributed mainly in highlands across Middle America, all adapted to arboreal habitats. Bothriechis supraciliaris is a relatively recently ...
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 ...
Antivenomics of Atropoides mexicanus and Atropoides picadoi snake venoms: Relationship to the neutralization of toxic and enzymatic activities
(2010-09-30)
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’ ...
Venomous snakes of Costa Rica: biological and medical implications of their venom proteomic profiles analyzed through the strategy of snake venomics
(Journal of Proteomics XX (2014) XXX – XXX, Available online 24 February 2014, 2014-02-24)
In spite of its small territory of ~50,000 km2, Costa Rica harbors a remarkably rich biodiversity. Its herpetofauna includes 138 species of snakes, of which sixteen pit vipers (family Viperidae, subfamily Crotalinae), five ...
Snake venomics of the pit vipers Porthidium nasutum, Porthidium ophryomegas, and Cerrophidion godmani from Costa Rica: Toxicological and taxonomical insights
(2012-02-16)
Within the Neotropical pit vipers, a lineage of primarily Middle American snake species
referred to as the “Porthidium group” includes the genera Atropoides, Cerrophidion, and
Porthidium. In this study, the venom proteomes ...
Venomic and antivenomic analyses of the Central American coral snake, Micrurus nigrocinctus (Elapidae)
(2011-01-31)
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 ...
