Characterization of Pasteurella multocida associated with ovine pneumonia using multi-locus sequence typing (MLST) and virulence-associated gene profile analysis and comparison with porcine isolates.

Pasteurella multocida is a pathogen causing disease in a wide range of hosts including sheep and pigs. Isolates from ovine pneumonia were characterized by MLST (Multi-host and RIRDC databases) and virulence-associated gene (VAG) typing and compared with porcine isolates. Ovine and porcine isolates did not share any STs as determined by both schemes and exhibited different VAG profiles.
