The use of ELISA to determine antisnake venom potency of horse immune sera should provide benefits of costs and reproducibility compared to in vivo assays. In the present investigation we evaluated the correlation between ELISA antibody levels and in vivo neutralization assays. For the indirect ELISA method, 0.016 micrograms/well of Bothrops jararaca or Crotalus durissus terrificus venom were used to coat the plates and 100 microliters/well of each sample of antibothropic or anticrotalic venom sera were used at 1:10,000 dilution. Sheep anti-horse IgG conjugated to peroxidase was added and the substrate H2O2/o-phenylenediamine produced the color that was read at 492 nm. A correlation coefficient of r = 0.97 was found for anticrotalic venom antibodies and no significant correlation was observed for antibothropic venom sera using 16 serum samples from immunized horses. However, when three antibothropic venom sera showing high in vivo neutralization potency and low absorbance in ELISA or high absorbance values and low in vivo protection were not included in the correlation analysis the coefficient value was r = 0.88. The correlation coefficient did not improve for all 16 antibothropic sera when a partially purified Bothrops jararaca venom fraction was used to coat the ELISA plates. The results indicate that ELISA could be used to determine the neutralizing potency of anticrotalic venom sera. For the antibothropic venom sera further studies are needed.
