Caprylic acid fractionation of hyperimmune horse plasma: description of a simple procedure for antivenom production
(1994)
A simple methodology for hyperimmune horse plasma fractionation, based on caprylic acid precipitation, is described. Optimal conditions for fractionation were studied; the method gives best results when concentrated caprylic ...
An alternative in vitro method for testing the potency of the polyvalent antivenom produced in Costa Rica
(1988)
The ability of several batches of polyvalent antivenom to neutralize indirect hemolytic activity of Bothrops asper venom was studied using a sensitive plate test. All samples of antivenom tested effectively neutralized ...
Inhibition of toxic activities of Bothrops asper venom and other crotalid snake venoms by a novel neutralizing mixture
(1997-12)
The majority of snake bites in Central America are caused by Bothrops asper, whose venom induce complex local effects such as myonecrosis, edema and especially hemorrhage. These effects are only partially neutralized by ...
Inhibition by CaNa2EDTA of local tissue damage induced by Bothrops asper (terciopelo) venom: Application in horse immunization for antivenom production
(1998-03-26)
The ability of the chelating agent CaNa2EDTA to inhibit local tissue damage induced by Bothrops asper venom was studied in mice and in horses used for polyvalent (Crotalinae) antivenom production. CaNa2EDTA was devoid of ...
A new method for the detection of phospholipase A2 variants: identification of isozymes in the venoms of newborn and adult Bothrops asper (terciopelo) snakes
(1988)
A new method for the identification of phospholipase A2 isozymes in snake venoms is described. The technique is based on the separation of the venom components by isoelectric focusing in agarose gels, transfer of the protein ...
Turbidity of hyperimmune equine antivenom: the role of phenol and serum lipoproteins
(1993)
Twenty batches of polyvalent antivenom produced at the Instituto Clodomiro Picado were analyzed for turbidity, both before and after freezing-thawing and lyophilization. Eight batches became turbid upon freezing-thawing, ...
Selecting key toxins for focused development of elapid snake antivenoms and inhibitors guided by a Toxicity Score
(2015-09-15)
For more than 100 years, antivenoms have been produced by traditional methods of immunization of large mammals with mixtures of snake venoms (World Health Organization, 2010 and Gutiérrez et al., 2011). With the introduction ...
A comparison of in vitro methods for assessing the potency of therapeutic antisera against the venom of the coral snake Micrurus nigrocinctus
(1997-04)
Therapeutic antisera against Micrurus nigrocinctus venom were tested for protection against lethality, as well as for inhibition of the nicotinic acetylcholine receptor (AchR)-binding and neutralization of phospholipase ...
The Need for Full Integration of Snakebite Envenoming within a Global Strategy to Combat the Neglected Tropical Diseases: The Way Forward
(2013-06-13)
Snakebite envenoming constitutes a serious medical condition that primarily affects residents of rural communities in Africa, Asia, Latin America, and New Guinea [1], [2]. It is an occupational, environmental, and domestic ...
Pathological and biochemical changes induced in mice after intramuscular injection of venom from newborn specimens of the snake Bothrops asper (Terciopelo)
(1992-09)
Venom from newborn Bothrops asper snakes has higher lethal, hemorrhagic, edema-forming, proteolytic and defibrinating activities than venom from adult B. asper specimens. Electrophoretic analysis confirmed the variation ...
