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 of Bothriechis nigroviridis reveals extreme variability among palm pitviper venoms: different evolutionary solutions for the same trophic purpose
(2010)
We report the proteomic characterization and biological activities of the venom of the black-speckled palm pitviper, Bothriechis nigroviridis, a neotropical arboreal pitviper from Costa Rica. In marked contrast to other ...
Comparative study of synthetic peptides corresponding to region 115-129 in Lys49 myotoxic phospholipases A2 from snake venoms
(2003)
Lys49 phospholipase A2 homologues constitute a group of catalytically-inactive proteins, present in the venoms of many
crotalid snakes, which induce myonecrosis. Current evidence supports the mapping of their toxic site ...
Isolation and characterization of four medium-size disintegrins from the venoms of Central American viperid snakes of the genera Atropoides, Bothrops, Cerrophidion and Crotalus
(2014-12)
Four disintegrins were isolated from the venoms of the Central American viperid snakes Atropoides mexicanus (atropoimin), Bothrops asper (bothrasperin), Cerrophidion sasai (sasaimin), and Crotalus simus (simusmin). ...
Isolation of two basic phospholipases A2 from Bothrops diporus snake venom: comparative characterization and synergism between Asp49 and Lys49 variants
(2019)
Bothrops diporus, previously considered a subspecies of the B. neuwiedi complex, is a medically relevant viperid in
Northeastern Argentina. The venom of this species causes local tissue damage characterized by ...
Immunochemical properties of the N-terminal helix of myotoxin II, a lysine-49 phospholipase A2 from Bothrops asper snake venom
(2001)
Myotoxic class II phospholipases A2 from snake venoms can be divided into Asp49 and Lys49 types. The latter, including
Bothrops asper myotoxin II, exert membrane damage despite lacking catalytic activity. A heparin-binding, ...
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 ...
Characterization of a basic phospholipase A2-homologue myotoxin isolated from the venom of the snake Bothrops neuwiedii (yarará chica) from Argentina
(1999)
A basic protein was isolated by CM-Sephadex C-25 chromatography from the venom of
Bothrops neuwiedii from Argentina, and named B. neuwiedii myotoxin I. This protein
exerted local myotoxic and edema-forming e ects in mice, ...
Comparative study of the cytolytic activity of snake venoms from African spitting cobras (Naja spp., Elapidae) and its neutralization by a polyspecific antivenom
(2011-11)
Venoms of several Naja species found in Sub-Saharan Africa, and commonly known as "spitting cobras", induce a predominantly cytotoxic pattern of envenomings that may evolve into tissue necrosis and gangrene. Cytotoxic ...
Isolation and characterization of myotoxin II from Atropoides (Bothrops) nummifer snake venom, a new Lys49 phospholipase A2 homologu
(2000)
Myotoxic phospholipases A2 of class II are commonly found in the venoms of crotalid snakes. As an approach to
understanding their structure±activity relationship, diverse natural variants have been characterized ...
