Serological tests as indicators of immunity against Pasteurella multocida infection in sheep
Abstract:
Five serological tests, i.e. single tube agglutination, doubling dilution tube agglutination, agar agglutination, passive hemagglutination and passive mouse protection tests were evaluated for their efficacy in predicting the fate of vaccinated and unvaccinated sheep on challenge with an ovine strain of Pasteurella multocida. The passive hemagglutination test predicted the fate of unvaccinated sheep while the agar agglutination test indicated the immune status of vaccinated sheep.
