“…In other cases, antivenoms are able to neutralize the venoms of species not used in the immunization of animals, but being phylogenetically related (WHO, 2010a). This phenomenon of immunological cross-reactivity has been clearly demonstrated, for instance, in the case of antivenoms raised against Bothrops sp venoms in Latin America (Otero et al, 1995;Segura et al, 2010a). In other cases, however, the cross-reactivity of antivenoms is low and, therefore, the efficacy of some products to neutralize venoms of medically-relevant species not included in immunization mixtures is limited, as occurs with venoms of some rattlesnakes and coral snakes in the Americas (Saravia et al, 2002;Tanaka et al, 2010).…”

“…For the control groups, venom was incubated with PBS instead of antivenom. Then, the mixtures were incubated at 37 C for 30 min and residual toxicity was assessed in mouse models (CD-1 mice of both sexes from Instituto Clodomiro Picado) or, in the case of coagulant, proteolytic and PLA 2 activities, by in vitro tests previously described (ICP, 2008;Segura et al, 2010). When performing in vivo experiments, mice were kept in plastic cages, with water and food ad libitum under controlled temperature conditions.…”

“…La DL 50 determinada en el presente trabajo (3,3±0,5μg/g de ratón) está en el intervalo de 58-100 µg /ratón descrito por Segura A. et al (29) mostrando que el veneno utilizado es un referente de buena potencia.…”
