Why myotoxin-containing snake venoms possess powerful nucleotidases?
(2013-01-25)
The venom of the snake Bothrops asper causes muscle necrosis, pain and inflammation. This venom contains myotoxins which cause an increase in intracellular Ca2+ concentration and release of K+ and ATP from myotubes. ATP ...
Neutralization of myonecrosis, hemorrhage, and edema induced by Bothrops asper snake venom by homologous and heterologous pre-existing antibodies in mice
(1996)
The ability of pre-existing antibodies to neutralize locally-acting toxins of Bothrops
asper snake venom was investigated. Hemorrhage, myonecrosis, and edema
were markedly reduced in actively immunized mice, although ...
Venom of the Coral Snake Micrurus clarki: Proteomic Profile, Toxicity, Immunological Cross-Neutralization, and Characterization of a Three-Finger Toxin
(2016)
Micrurus clarki is an uncommon coral snake distributed from the Southeastern Pacific of Costa Rica to Western Colombia, for which no information on its venom could be found in the literature. Using a 'venomics' approach, ...
Edema-forming activity of bushmaster (Lachesis muta stenophrys) and Central American rattlesnake (Crotalus durissus durissus) venoms and neutralization by a polyvalent antivenom
(1985)
The edema effect induced in mice by venoms of Crotalus durissus durissus and Lachesis muta stenophrys was studied . Minimum edema-forming doses were 11 and 5 ug, respectively . Edema developed very rapidly after injections ...
Comparative study on coagulant, defibrinating, fibrinolytic and fibrinogenolytic activities of Costa Rican crotaline snake venoms and their neutralization by a polyvalent antivenom
(1989)
The coagulant, defibrinating, fibrino lytic and fibrinogenolytic activities of venoms from ten species of Costa Rican crotaline snakes were studied, together with the neutralization of these effects by a polyvalent antivenom. ...
Neutralization, by a monospecific Bothrops lanceolatus antivenom, of toxic activities induced by homologous and heterologous Bothı́rops snake venoms
(1999-03)
A monospecific Bothrops lanceolatus antivenom, currently used in Martinique, was tested for its efficacy in the neutralization of several toxic and enzymatic activities of the venoms of B. lanceolatus, B. atrox and B. ...
A new method for the detection of phospholipase A2 variants: identification of isozymes in the venoms of newborn and adult Bothrops asper (terciopelo) snakes
(1988)
A new method for the identification of phospholipase A2 isozymes in snake venoms is described. The technique is based on the separation of the venom components by isoelectric focusing in agarose gels, transfer of the protein ...
Inhibitory effect of fucoidan on the activities of crotaline snake venom myotoxic phospholipases A2
(2003)
Myotoxic phospholipases A2 account for most of the muscle necrosis that results from envenenomation by crotaline snakes. In this study,
we investigated the protective effect of fucoidan, a natural sulfated polysaccharide ...
Snake venom Lys49 myotoxins: from phospholipases A2 to non-enzymatic membrane disruptors
(2012-09)
Snake venoms often contain toxins that cause a rapid necrosis of skeletal muscle fibers,
referred to as myotoxins. The most common among them are phospholipases A2 (PLA2s),
enzymes that have two independent evolutionary ...
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 ...
