The ompA gene of Pasteurella multocida serotype B: 2 (strain P52) was cloned in InsT/A vector for sequencing and gene sequence was compared with that of other strains (232, 95010872, T94289 and 95120769) of serogroup A. It revealed a 1077 nucleotide and it had additional 30 bp than that of serotype A: 3. About 11.5 to 14% divergence in ompA gene sequence was observed between serotype B: 2 and various strains of serogroup A of P. multocida. A variation of about 20% in the amino acid sequence of outer membrane protein A (OmpA) was also recorded between serogroups A and B.
