Reactivity of Hyperimmune bovine colostrums (HBC) against RRV. HBC preparation is highly reactive against RRV as assessed by ELISA. ELISA plates were coated with RRV and HBC was added in different dilutions. The reaction was developed using anti-bovine AP conjugated secondary antibody. Control colostrums preparation (Imulin^®) does not show any cross-reactivity with RRV even at high concentrations.
