Abstract

Ninety-one isolates of Pasteurella multocida (Pm) and 124 of Pasteurella haemolytica (Ph) were recovered from the lungs of calves that diedof bovine respiratory tract disease (BRTD). Nine Pm enzyme profiles (A through I) and 9 Ph enzyme profiles (J through R) were determined for the Pasteurella isolates. The Pm isolates were relatively evenly divided among the enzyme profiles, with one exception, profile I. The Ph isolates were not evenly distributed among the profiles, Fifty of the 91 Pm isolates were serotyped. Forty-two Pm isolates were positive forcapsule type A, and 8 were untypable, Five somatic type antigen profiles (3; 3,4; 3,7; 3,4,7; and 4) were identified among the 50 serotypedPm isolates; one isolate was untypable. The Ph isolates were further divided through serotyping and grouped as follows: 74 (60%) Pasteurella haemolytica A1 (PhA1), 12 (10%) PhA2, 4 (3%) PkAS, and 34 (27%) PhA6. Eighty-one percent of the Ph serotypes were clustered in the M and Nenzyme profile. The P enzyme profile was almost unique to PhA2 (8 of 12, 67% of PhA2 isolates), Results of this study indicate a need to collect more data on Ph serotypes at the state veterinary diagnostic laboratories.
