Development of a chicken-derived antivenom against the taipan snake (Oxyuranus scutellatus) venom and comparison with an equine antivenom
(2016-09-15)
A chicken-derived antivenom (ChDAv) towards taipan snake (Oxyuranus scutellatus) venom was produced
by purifying anti-taipan IgY from egg yolks of hens immunized with taipan venom. The productivity,
antivenomic profile, ...
Neutralization of Bothrops mattogrossensis snake venom from Bolivia: Experimental evaluation of llama and donkey antivenoms produced by caprylic acid precipitation
(2010-02-01)
Polyspecific bothropic/crotalic and bothropic/lachesic antivenoms were produced in Bolivia by immunizing two donkeys with the venoms of Bothrops mattogrossensis and Crotalus durissus terrificus and one llama with the venoms ...
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 ...
Stability of equine IgG antivenoms obtained by caprylic acid precipitation: Towards a liquid formulation stable at tropical room temperature
(2009-05)
Liquid formulations of antivenom require a cold chain for their distribution and storage, especially in tropical countries characterized by high temperature and humidity (climatic zone IV). Since cold chain is often deficient ...
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, ...
Toxicity of Bothrops sp snake venoms from Ecuador and preclinical assessment of the neutralizing efficacy of a polyspecific antivenom from Costa Rica
(2014-09-15)
The toxicological profile of the venoms of the snakes Bothrops asper and Bothrops atrox from Ecuador was investigated, together with the venom of a population of B. asper formerly classified as ‘Bothrops xanthogrammus’. ...
Study of the design and analytical properties of the lethality neutralization assay used to estimate antivenom potency against Bothrops asper snake venom
(2010-09)
The lethality neutralization assay performed in mice is the standard recommended by the World Health Organization to estimate antivenom potency. The interpretation of its results without considering its analytical capacity ...
Pathogenesis of dermonecrosis induced by venom of the spitting cobra, Naja nigricollis: An experimental study in mice
(2016-09-01)
The pathogenesis of dermonecrosis induced by the venom of the African spitting cobra Naja nigricollis was investigated in a mouse model. Intradermal injection of venom induced a macroscopic necrotic lesion. Histological ...
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 ...
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 ...
