Ability of six Latin American antivenoms to neutralize the venom of mapaná equis (Bothrops atrox) from Antioquia and Chocó (Colombia)
(1995-06)
This investigation compared the ability of six Latin American antivenoms (monovalent antibothropic INS, Santafé de Bogotá; polyvalent INS; polyvalent probiol, Santafé de Bogotá; antibothropic Instituto Butantan, IB, São ...
Snakebites are associated with poverty, weather fluctuations, and El Niño
(2015-09-11)
Snakebites are environmental and occupational health hazards that mainly affect rural populations worldwide. The ectothermic nature of snakes raises the issue of how climate change’s impact on snake ecology could influence ...
Local tissue damage induced by Bothrops snake venoms - A review
(1989-12)
This review focuses on the local effects induced by Bothrops venoms. These envenomation are characterized by myonecrosis, hemorrhage and edema which develop rapidly after venom inoculation. Myonecrosis is caused (a) directly, ...
High-throughput immuno-profiling of mamba (Dendroaspis) venom toxin epitopes using high-density peptide microarrays
(2016-11-08)
Snakebite envenoming is a serious condition requiring medical attention and administration of
antivenom. Current antivenoms are antibody preparations obtained from the plasma of animals
immunised with whole venom(s) and ...
Comprendiendo los venenos de serpientes: 50 años de investigaciones en América Latina
(2002)
As a tribute to Revista de Biología Tropical in its 50th anniversary, this review describes some of the main research efforts carried out in the study of the chemical composition and the mechanism of action of toxins present ...
Elapid venom toxins: multiple recruitments of ancient scaffolds
(1999-01)
Nigroxins A and B, two myotoxic phospholipases A2 (PLA2s) from the venom of the American elapid Micrurus nigrocinctus, belong to a new PLA2 subclass. Their primary structures were established and compared with those of ...
Local tissue damage induced by BaP1, a metalloproteinase isolated from Bothrops asper (Terciopelo) snake venom
(1995-12)
The pathogenesis of hemorrhage and other local effects induced by the metalloproteinase BaP1, isolated from Bothrops asper venom, was investigated using various in vivo and in vitro models. Upon intramuscular injection in ...
Isolation of a myotoxin from Bothrops asper venom: Partial characterization and action on skeletal muscle
(1984)
A myotoxic phospholipase has been isolated from Bothrops asper venom by ion-exchange chromatography on CM-Sephadex followed by gel filtration on Sephadex G-75. The toxin is a basic polypeptide with an estimated molecular ...
Quantitation of myonecrosis induced by myotoxin a from prairie rattlesnake (Crotalus viridis viridis) venom
(1982)
Using a pure myotoxin (myotoxin a) isolated from prairie rattlesnake Crotalus viridis viridis) venom, a comparison between two methods for quantitating myonecrosis in mice was made. Measurement of creatine kinase (CK) ...
Neutralization of proteolytic and hemorrhagic activities of Costa Rican snake venoms by a polyvalent antivenom
(1985)
The polyvalent antivenom produced at the Instituto Clodomiro Picado, Costa Rica, was tested for its capacity to neutralize proteolytic and hemorrhagic activities of ten Costa Rican crotaline venoms. In experiments with ...
