Naturally acquired Pasteurella multocida infection in rabbits: clinicopathological aspects

A cohort of 41 New Zealand White rabbits, 35 to 60 days old, from twelve litters were followed for twelve weeks for development of pasteurellosis. Eleven of 19 rabbits in five litters acquired Pasteurella multocida infection. The incubation period was difficult to determine as P. multocida infection was detected both before and after the onset of rhinitis. The response of rabbits to infection varied from subclinical infection to death from systemic pasteurellosis. Atrophy of the maxilloturbinates of the nares was detected in rabbits with chronic rhinitis associated with P. multocida infection.
