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 ... -
Anti-rotavirus antibody in human colostrum
(The Lancet 311(8054), 7 January 1978, Pages 39–40. Originally published as Volume 1, Issue 8054, 1978)During investigation of the epidemiology of human rotavirus infection in Costa Rica, the anti-human rotavirus capacity of colostrum was studied. We were looking for an explanation for the relatively low incidence of acute ... -
Antibiotics do not affect the degradation of fungicides and enhance the mineralization of chlorpyrifos in biomixtures
(2017)The use of antibiotics in agriculture produces residues in wastewaters. The disposal of such wastewaters in biopurification systems (BPS) employed for the treatment of pesticides could result in the inhibition of the ... -
Antibodies against a single fraction of Micrurus dumerilii venom neutralize the lethal effect of whole venom
(2023-02-01)The coralsnake Micrurus dumerilii (Elapidae) is reported to cause envenomings of medical importance. Previous studies characterized the protein composition of its venom, with phospholipase A2 (PLA2) proteins the most ... -
Antibody neutralization of a myotoxin from the venom of Bothrops asper (terciopelo)
(1987)Neutralization of biological activities of B. asper myotoxin by a monospecific anti-myotoxin rabbit serum and polyvalent antivenom was studied. Both antisera neutralized myotoxic, phospholipase A and lethal activities of ... -
Antibody-dependent enhancement of toxicity of myotoxin II from Bothrops asper
(2024)Improved therapies are needed against snakebite envenoming, which kills and permanently disables thousands of people each year. Recently developed neutralizing monoclonal antibodies against several snake toxins have ... -
Antibody-mediated neutralization and binding-reversal studies on α-neurotoxins from micrurus nigrocinctus nigrocinctus (coral snake) venom
(1996-03)An ELISA based, non-radioactive acetylcholine receptor (AchR) binding assay was used to detect the alpha-neurotoxins present in Micrurus nigrocinctus nigrocinctus venom. Sera from horses hyperimmunized against M. nigrocinctus ... -
Anticomplementary activity of equine whole IgG antivenoms: comparison of three fractionation protocols
(2005-01)Early adverse reactions occur in a number of patients treated with heterologous antivenoms and have been associated with anticomplementary activity (ACA). In order to reduce the ACA of equine whole IgG antivenoms produced ... -
Anticomplementary Activity of Horse IgG and F(ab’)2 Antivenoms
(2014)Envenomation by poisonous animals is a neglected condition according to the World Health Organization (WHO). Antivenoms are included in the WHO Essential Medicines List. It has been assumed that immunoglobulin G (IgG) ... -
Anticuerpos IgE específicos de alergenos comunes en niños costarricenses
(Alergia, Asma e Inmunología Pediátricas :13 (2); p 40-43, 2004-05)La morbilidad por asma y otras enfermedades alérgicas aumentan cada año y un factor muy importante es la exposición a niveles elevados de alergenos interiores. En el presente estudio se evaluó la prevalencia y la exposición ... -
Antimicrobial activity of myotoxic phospholipases A2 from crotalid snake venoms and synthetic peptide variants derived from their C-terminal region
(2005)A short peptide derived from the C-terminal region of Bothrops asper myotoxin II, a Lys49 phospholipase A2 (PLA2), was previously found to reproduce the bactericidal activity of its parent molecule. In this study, a panel ... -
Antiplasmodial effect of the venom of Crotalus durissus cumanensis, crotoxin complex and Crotoxin B
(2012-11)The antiplasmodial activity of phospholipases A2 (PLA2) isolated from different animals has been studied. We explored the in vitro anti Plasmodium falciparum effect of a fraction containing crotoxin, Crotoxin B and whole ... -
Antitumor effects of cationic synthetic peptides derived from Lys49 phospholipase A2 homologues of snake venoms
(2007)The effects of two cationic synthetic peptides, derived from the C-terminal region of Lys49 phospholipase A2 homologues from snake venoms, upon various murine tumor cell lines (B16 melanoma, EMT6 mammary carcinoma, S-180 ... -
Antivenom for snakebite envenoming in Sri Lanka: The need for geographically specific antivenom and improved efficacy
(2013-07)Sri Lanka is a tropical developing island nation that endures significant economic and medical burden as a result of snakebite envenomation, having not only a high prevalence of envenomations, but also one of the highest ... -
Antivenomic Assessment of the Immunological Reactivity of EchiTAb-Plus-ICP, an Antivenom for the Treatment of Snakebite Envenoming in Sub-Saharan Africa
(2010)The immunoreactivity of EchiTAb-Plus-ICP, an antivenom developed for the treatment of snakebite envenoming in sub-Saharan Africa, to venoms of seven Echis and Bitis species, was assessed by “antivenomics.” This proteomic ... -

(2014-11-05)Antivenoms manufactured by bioCSL Limited (Australia) and Instituto Clodomiro Picado (Costa Rica) against the venom of the taipan snakes (Oxyuranus scutellatus) from Australia and Papua New Guinea (PNG), respectively, were ... -
Antivenomics and in vivo preclinical efficacy of six Latin American antivenoms towards south-western Colombian Bothrops asper lineage venoms
(2021)Snakebite envenoming is an important occupational health problem, particularly in rural areas of developing countries. The timely administration of an effective antivenom remains the mainstay of snakebite management. ... -
Antivenomics of Atropoides mexicanus and Atropoides picadoi snake venoms: Relationship to the neutralization of toxic and enzymatic activities
(2010-09-30)Viperid snakes of the genus Atropoides are distributed in Mexico and Central America and, owing to their size and venom yield, are capable of provoking severe envenomings in humans. This study evaluated, using an ‘antivenomics’ ... -
