Popis: Thirty strains of Pasteurella haemolytica which were untypable by the indirect haemagglutination (IHA) test were examined serologically by rapid plate agglutination (RPA), agar gel diffusion (AGD), crossed immunoelectrophoresis (CIE) and counter current immunoelectrophoresis (CCIE) tests. Nine serogroups were identified by CCIE. Serogroup specificity, dependent on two antigens, was present in heated saline extracts of cells. Single representative strains from two serogroups were not pathogenic for specific pathogen-free lambs.
