Neutralization of lethality of venoms by monospecific antisera (see materials and methods for details). Neutralization is expressed as the median effective dose (ED₅₀), i.e., the ratio mg venom/mL antivenom at which 50% of the injected mice are protected. Bars correspond to the 95% confidence intervals. * Significantly different as compared to the homologous antisera. ↓ values under the detection limit of the lethality neutralization assay.
