Preclinical assessment of the neutralizing capacity of antivenoms produced in six Latin American countries against medically-relevant Bothrops snake venoms
(2010-11)
Species of the genus Bothrops induce the vast majority of snakebite envenomings in Latin America. A preclinical study was performed in the context of a regional network of public laboratories involved in the production, ...
Impact of Regional Variation in Bothrops asper Snake Venom on the Design of Antivenoms: Integrating Antivenomics and Neutralization Approaches
(2010-10-21)
Intraspecific snake venom variations have implications in the preparation of venom pools for the generation of antivenoms. The impact of such variation in the cross-reactivity of antivenoms against Bothrops asper venom was ...
Understanding and confronting snakebite envenoming: The harvest of cooperation
(2016-01)
During 45 years, the Instituto Clodomiro Picado (ICP, University of Costa Rica) has developed an ambitious scientific, technological, productive, and social program aimed at providing a better understanding of snakes and ...
Anti-human erythrocyte antibodies in horse-derived antivenoms used in the treatment of snakebite envenomations
(2007-03)
This work examined the presence of antibodies reacting with human erythrocytes in horse-derived antivenoms used in the treatment of snakebite envenomations, and assessed the efficacy of various fractionation protocols in ...
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 ...
Preclinical assessment of the efficacy of a new antivenom (EchiTAb-Plus-ICP) for the treatment of viper envenoming in sub-Saharan Africa
(2010-02)
A preclinical assessment was performed on the neutralizing efficacy of a whole IgG polyspecific antivenom (EchiTAb-Plus-ICP®), designed for the treatment of snakebite envenomings in Nigeria. It was generated by immunizing ...
Evaluation of the preclinical efficacy of four antivenoms, distributed in sub-Saharan Africa, to neutralize the venom of the carpet viper, Echis ocellatus, from Mali, Cameroon, and Nigeria
(2015-11)
Snakebite envenoming causes a heavy toll in sub-Saharan Africa in terms of mortality and sequelae. In the West African savannah, the viperid Echis ocellatus is responsible for the vast majority of bites. In the last decades, ...
Intravenous administration of equine-derived whole IgG antivenom does not induce early adverse reactions in non-envenomed horses and cows
(2010-11)
Administration of antivenoms to treat snakebite envenomings has the potential risk of inducing early adverse reactions. The mechanisms involved in these reactions are unclear. In this study, polyspecific antivenom consisting ...
Neutralization of four Peruvian Bothrops sp. snake venoms by polyvalent antivenoms produced in Perú and Costa Rica: preclinical assessment
(2005-06)
Envenomations after bites inflicted by snakes of the genus Bothrops constitute a public health hazard in Perú, and the intravenous administration of equine-derived antivenoms represents the only scientifically validated ...
Role of the animal model on the pharmacokinetics of equine-derived antivenoms
(2013-08)
Antivenom pharmacokinetics has been studied in heterologous models in which the animal species used as immunoglobulin source is different from that used as recipient. In these models, after intravenous administration of ...
