| Summary: | The serum antibody response elicited in the equine, over a five-year period, when vaccinated with either a modified-live (ERA) or an inactivated (Trimune) rabies vaccine was evaluated by the RFFIT and the ELISA. The ELISA, utilizing whole virion inactivated rabies vaccine for the coating antigen, was developed. This ELISA detected levels of the immunoglobulin lgG (H+L), the major immunoglobulin produced in response to infection with rabies virus. This ELISA appeared to be more sensitive than the RFFIT. The RFFIT detected levels of serum neutralizing antibodies, an indicator in vitro of the level of protection conferred by the immune response in vivo. The Trimune vaccine group produced higher levels of antibody in the first year. However, the ERA group demonstrated higher levels in the subsequent years. The modified-live vaccine (ERA) conferred a 100% level of positive immunity during the last two years when no vaccination program was implemented. This evaluation of the immune response in the equine can serve as a guide for equine managers in implementing vaccination programs. The ELISA developed was successful in detecting antigen-antibody complexes prior to detection of neutralizing antibodies. This should prove useful as a diagnostic tool in the early detection of rabies infection. |
