First crotoxin-like phospholipase A2 complex from a New World non-rattlesnake species: Nigroviriditoxin, from the arboreal Neotropical snake Bothriechis nigroviridis
(Toxicon vol 93:144–154, 2015-01)
Bothriechis nigroviridis is an arboreal Neotropical pitviper found in Costa Rica and Panam a. A previous
proteomic profiling of its venom revealed the presence of proteins with homology to the A and B subunits
of ...
Pathological changes induced by BaH1, a hemorrhagic proteinase isolated from Bothrops asper (Terciopelo) snake venom, on mouse capillary blood vessels
(1994-08)
The pathological changes induced in capillaries by BaH1, a hemorrhagic metalloproteinase isolated from the venom of Bothrops asper, were studied after i.m. injection in mouse gastrocnemius. Hemorrhage was observed ...
Calcium imaging of muscle cells treated with snake myotoxins reveals toxin synergism and presence of acceptors
(2009-04-17)
Snake myotoxins have a great impact on human health worldwide. Most of them adopt a phospholipase A2 fold and occur in two forms which often co-exist in the same venom: the Asp49 toxins hydrolyse phospholipids, whilst Lys49 ...
Poor regenerative outcome after skeletal muscle necrosis induced by Bothrops asper venom: alterations in microvasculature and nerves
(PLoS ONE 6(5): e19834, 2011-05-24)
Background: Viperid snakebite envenoming is characterized by prominent local tissue damage, including muscle necrosis. A frequent outcome of such local pathology is deficient skeletal muscle regeneration, which causes ...
Phospholipases a2 from Viperidae snakes: Differences in membranotropic activity between enzymatically active toxin and its inactive isoforms
(Biochimica et Biophysica Acta - Biomembranes vol 1848: 463–468, 2015-02)
We describe the interaction of various phospholipases A2 (PLA2) from snake venoms of the family Viperidae
(Macrovipera lebetina obtusa, Vipera ursinii renardi, Bothrops asper) with giant unilamellar vesicles (GUVs)
composed ...
A eficácia do antiveneno botrópico-crotálico na neutralização das principais atividades do veneno de Bothrops jararacussu
(1992)
Myonecrosis is one of the effects of Bothrops jararacussu venom, from which a myotoxin was isolated showing structural homology to phospholipase A2 (PLA2), but without enzimatic activity. Such myotoxic activity is also ...
Snake venomics and antivenomics of Bothrops colombiensis, a medically important pitviper of the Bothrops atrox-asper complex endemic to Venezuela: Contributing to its taxonomy and snakebite management
(2009-03-06)
The taxonomic status of the medically important pitviper of the Bothrops atrox-asper complex endemic to Venezuela, which has been classified as Bothrops colombiensis, remains incertae cedis. To help resolving this question, ...
Comparison between IgG and F(ab′)2 polyvalent antivenoms: neutralization of systemic effects induced by Bothrops asper venom in mice, extravasation to muscle tissue, and potential for induction of adverse reactions
(2001-06)
Whole IgG and F(ab′)2 equine-derived polyvalent (Crotalinae) antivenoms, prepared from the same batch of hyperimmune plasma, were compared in terms of neutralization of the lethal and defibrinating activities induced by ...
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 ...
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 ...
