Abstract

A coagglutination test was described for simple, fast and reliable detection of Pasteurella haemolytica typespecific antigens in lung lesions even if no viable bacteria could be cultured. Reactions using bacterial suspensions, saline extracts and boiled saline extracts as antigens were similar to that obtained by the indirect haemagglutination test. Sixty one out of 65 P. haemolytica field strains could be serotyped using the coagglutination test and P. haemolytica typespecific antigens were detected in the lung specimens of 3 calves and 5 sheep succumbed due to naturally occurring pneumonia caused by P. haemolytica and 20 calves experimentally infected with P. haemolytica A1. The coagglutination test detected typespecific antigens in 36% of the lung specimens of slaughtered field sheep. No false positive or negative reactions occurred. This test is recommended as an additional method for fast and reliable serotyping of P. haemolytica.
