Skeletal muscle necrosis and regeneration after injection of Thalassophryne nattereri (niquim) fish venom in mice
Stings by Thalassophryne nattereri are responsible for envenomation of fishermen in north-eastern Brazil. Its venom induces prominent local tissue damage, characterized by pain, oedema and necrosis. The pathogenesis of ...
Antibody neutralization of a myotoxin from the venom of Bothrops asper (terciopelo)
Neutralization of biological activities of B. asper myotoxin by a monospecific anti-myotoxin rabbit serum and polyvalent antivenom was studied. Both antisera neutralized myotoxic, phospholipase A and lethal activities of ...
Venom of the crotaline snake Atropoides nummifer (jumping viper) from Guatemala and Honduras: comparative toxicological characterization, isolation of a myotoxic phospholipase A(2) homologue and neutralization by two antivenoms
A comparative study was performed on the venoms of the crotaline snake Atropoides nummifer from Guatemala and Honduras. SDS-polyacrylamide gel electrophoresis, under reducing conditions, revealed a highly similar pattern ...
Myonecrosis induced in mice by a basic myotoxin isolated from the venom of the snake Bothrops nummifer (jumping viper) from Costa Rica
The mode of action of a basic myotoxin isolated from Bothrops nummifer venom was studied. This myotoxin is a basic polypeptide of 13,000 mol.wt, with a high content of lysine and aspartate, as well as of hydrophobic amino ...
Two color morphs of the pelagic yellow-bellied sea snake, pelamis platura, from different locations of Costa Rica: snake venomics, toxicity, and neutralization by antivenom
(Journal of Proteomics Volume 103, 30 May 2014, Pages 137–152, 2014-05-30)
The yellow-bellied sea snake, Pelamis platura, is the most broadly distributed snake species. Despite being endowed with a highly lethal venom, a proteomic analysis of its toxin composition was unavailable. The venoms of ...
Dissociation of enzymatic and toxic activities by the use of antibodies
Disociación de las actividades enzimáticas y tóxicas mediante la utilización de anticuerpos
IN A RECENT article KASTURi and GOWDA,(1990) described the dissociation of enzymatic and toxic activities of phospholipases A, (PLA) from Vipera russelli venom by neutraliza- tion experiments u ...
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 ...
Ontogenetic changes in the venom of the snake Lachesis muta stenophrys (bushmaster) from Costa Rica
A comparative study was performed on some enzymatic and toxic activities of venoms collected from newborn, one-year old, two-years old and adult (more than five-years old) specimens of Lachesis muta stenophrys. There was ...
Myotoxin II from Bothrops asper (Terciopelo) venom is a lysine-49 phospholipase A2
A basic, dimeric myotoxic protein, myotoxin II, purified from Bothrops asper venom has a similar molecular weight and is immunologically cross-reactive with antibodies raised to previously isolated B. asper phospholipases ...
