ANTIGENIC CHARACTERISATION OF Pasteurella multocida ISOLATES FROM RABBITS-II

Individually antiserum against three forms of antigens viz.., heat inactivated crude extract, KSCN extract and Sonicated antigen from the three strains of P. multocida was raised ut rabbits. Serological tests such as AGPT, Immunoelectr ophoresis and IHA were carried out to compare the antigenic relationship of the isolates. Each antiserum was tested against three homologous and two heterologous antigens and it prominent with antiserum raised against sonicated antigen. These results were in continuity with the results of Sawada et al. (1982) with crude extract and KSCN extract antigen. The present results were in absolute confirmity with the results obtained by Azam et al. (1991) wherein they reported adore-dependent immune response
