ANTIBODIES DETECTION TO RHODOCOCCUS EQUI IN VACCINATED MARES AND FOALS BY INDIRECT ENZYME IMMUNOASSAY

The humoral immune response in ‘Brasileiro de Hipismo’ (BH) breed and Breton mares was compared after using the Rhodococcus equi vaccine, and the effect of maternal immunoprophylaxis on antibody transfer to newborn foals through the colostrum was evaluated. Blood samples were obtained from 16 pregna...

Description
Summary:The humoral immune response in ‘Brasileiro de Hipismo’ (BH) breed and Breton mares was compared after using the Rhodococcus equi vaccine, and the effect of maternal immunoprophylaxis on antibody transfer to newborn foals through the colostrum was evaluated. Blood samples were obtained from 16 pregnant mares vaccinated against R. equi, 16 foals (offspring from vaccinated mares), 8 unvaccinated pregnant mares and 8 foals (offspring from control mares). R equi serum antibody titers were determined by enzyme-linked immunosorbant assay (ELISA) after the immunization of pregnant mares using two different antigens, APTX and the commercial vaccine. There was no difference in antibody production between the two breeds. Significant increase in R. equi antibody titers was observed in mares after vaccination (p
