Naturally acquired Pasteurella multocida subsp. multocida infection in a closed colony of rabbits: characteristics of isolates.
Twelve litters, comprising 41 rabbits aged 35 to 60 days old, in a closed university colony, were monitored for acquisition of nasal Pasteurella multocida subsp. multocida infection. Isolates from 11 infected rabbits were characterized by colonial morphology, capsular type, biotype and antibiotic resistance. Selected isolates were further characterized by somatic antigen typing. Two major strains of P. multocida subsp. multocida were detected in the colony. One strain had mucoid colonies, fermented few carbohydrates and was serotype A:5, whereas, the other strain had smooth iridescent colonies, non-typeable capsular antigen, type 3 somatic antigen and fermented more than twice as many carbohydrates.
