Snake venomics of the South and Central American Bushmasters. Comparison of the toxin composition of Lachesis muta gathered from proteomic versus transcriptomic analysis
(2008-04-30)
We report the proteomic characterization of the venoms of two closely related pit vipers of the genus Lachesis, L. muta (South American Bushmaster) and L. stenophrys (Central American Bushmaster), and compare the toxin ...
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 ...
Integrated “omics” profiling indicates that miRNAs are modulators of the ontogenetic venom composition shift in the Central American rattlesnake, Crotalus simus simus
(2013)
Background
Understanding the processes that drive the evolution of snake venom is a topic of great research interest in molecular and evolutionary toxinology. Recent studies suggest that ontogenetic changes in venom ...
Snake Venomics of the Central American Rattlesnake Crotalus simus and the South American Crotalus durissus Complex Points to Neurotoxicity as an Adaptive Paedomorphic Trend along Crotalus Dispersal in South America
(2010)
We report a comparative venomic and antivenomic characterization of the venoms of newborn and adult specimens of the Central American rattlesnake, Crotalus simus, and of the subspecies cumanensis, durissus, ruruima, and ...
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 ...
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 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 ...
Snake Venomics of Central American Pitvipers: Clues for Rationalizing the Distinct Envenomation Profiles of Atropoides nummifer and Atropoides picadoi
(2008)
We report the proteomic characterization of the Central American pitvipers Atropoides nummifer and
Atropoides picadoi. The crude venoms were fractionated by reverse-phase high-performance liquid
chromatography (HPLC), ...
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, ...
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 ...
