Feeding behavior and venom toxicity of coral snake Micrurus nigrocinctus (Serpentes: Elapidae) on its natural prey in captivity
(2004-08)The feeding behavior and venom toxicity of the coral snake Micrurus nigrocinctus (Serpentes: Elapidae) on its natural prey in captivity were investigated. Coral snakes searched for their prey (the colubrid snake Geophis ... -
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 ... -
First look into the venom of Roatan Island´s critically endangered coral snake Micrurus ruatanus: proteomic characterization, toxicity, immunorecognition and neutralization by an antivenom
(2019)A proteomic and toxicological study of the venom from one specimen of Micrurus ruatanus, a critically endangered coral snake species endemic to Roatan Island, Honduras, was carried out. Immunorecognition and neutralization ... -

Freeze-dried snake antivenoms formulated with sorbitol, sucrose or mannitol: Comparison of their stability in an accelerated test
(2014-11)Freeze-drying is used to improve the long term stability of pharmaceutical proteins. Sugars and polyols have been successfully used in the stabilization of proteins. However, their use in the development of freeze-dried ... -
From Fangs to Pharmacology: The Future of Snakebite Envenoming Therapy
(2016)The snake is the symbol of medicine due to its association with Asclepius, the Greek God of medicine, and so with good reasons. More than 725 species of venomous snakes have toxins specifically evolved to exert potent ... -
Functional analysis of DM64, an antimyotoxic protein with immunoglobulin-like structure from Didelphis marsupialis serum
(2002-12-11)Bothrops snake venoms are known to induce local tissue damage such as hemorrhage and myonecrosis. The opossum Didelphis marsupialis is resistant to these snake venoms and has natural venom inhibitors in its plasma. The aim ... -
Functional, proteomic and transcriptomic characterization of the venom from Micrurus browni browni: identification of the first lethal multimeric neurotoxin in coral snake venom
(2020)Proteomic characterization of Micrurus browni browni venom showed approximately 41 components belonging to 9 protein families, mainly phospholipases A2 (PLA2s) and three-finger toxins (3FTxs). Venom gland transcriptome ... -
