El suero de neonatos de Clelia clelia (Serpentes: Colubridae) neutraliza la acción hemorrágica del veneno de Bothrops asper (Serpentes: Viperidae).
(1989)
The ability of serum from nine newbom specimens of Clelia clelia (Colubridae) to neutralize hernorrhagic action of Bothrops asper venom was tested. All serum samples neutralized completely the hernorrhagic effect of the ...
A novel pentameric phospholipase A2 myotoxin (PophPLA2) from the venom of the pit viper Porthidium ophryomegas
(2018-06-07)
The first toxin isolated from the venomous pit viper Porthidiumophryomegas is a basic pentameric phospholipase
A2 (PophPLA2). Elucidation of its amino acid sequence showed that it belongs to the group IIA of secreted ...
Ontogenetic variation in the venom of Mexican Jumping Viper (Metlapilcoatlus nummifer)
(2020)
The viperid genus Metlapilcoatlus (previously Atropoides) is represented in Mexico by four species: M. olmec, M. mexicanus, M. occidus, and M. nummifer. To date, no studies on their venoms have been reported. Here, we ...
Proteomic analysis of Bothrops pirajai snake venom and characterization of BpirMP, a new P-I metalloproteinase
(2013-03-27)
Bothrops pirajai snake venom was analyzed by a proteomic strategy. Proteins were separated by RP-HPLC, followed by SDS-PAGE, in-gel tryptic digestion, identification by MALDI-TOF/TOF mass spectrometry, and assignment to ...
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 ...
Immunological cross-recognition and neutralization studies of Micrurus mipartitus and Micrurus dumerilii venoms by two therapeutic equine antivenoms
(2020)
New world Coral snakes comprise 82 species of medical importance distributed from southeastern United States to Argentina. In Colombia, Micrurus mipartitus and M. dumerilii are responsible for most coral snakebite accidents. ...
Antivenomics: a proteomics tool for studying the immunoreactivity of antivenoms
(2015-03)
Envenoming following snakebite is largely a neglected threat to public health in tropical and subtropical regions of Africa, Asia, Latin America and Oceania addicting some of the world’s poorest rural communities. An ...
The recovery from the neuroparalysis caused by Micrurus nigrocinctus venom is accelerated by an agonist of the CXCR4 receptor
(2022)
Snake envenoming is a major but neglected human disease in tropical and subtropical regions. Among venomous snakes in the Americas, coral snakes of the genus Micrurus are particularly dangerous because they cause a peripheral ...
Utilidad de los péptidos sintéticos en estudios de estructura-función e identificación de epitopos en toxinas
(Bruno Lomonte. (2014). Utilidad de los péptidos sintéticos en estudios de estructura-función e identificación de epitopos en toxinas. Cuba: RED BIOTOX-CYTED. pp.71-80, 2014)
Los péptidos sintéticos han ganado un lugar relevante dentro de la “caja de herramientas” de la investigación biomédica actual. Las técnicas de síntesis automatizada y el costo decreciente de los procesos, unidas a mejoras ...
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 ...
