Prevalence of Bordetella bronchiseptica in cats attended by a veterinary practice in the Manawatu region.
OBJECTIVE
To determine the prevalence by isolation of Bordetella bronchiseptica infection in healthy cats and in cats showing signs of upper respiratory tract (URT) disease attended by a veterinary practice in the Manawatu region.


METHODS
The nasal cavity and oropharynx of 100 cats of mixed sex and age were swabbed and the swabs cultured for B. bronchiseptica. The population of cats surveyed was that attended by the Massey University Veterinary Teaching Hospital, and included healthy cats, cats with clinical signs of URT disease, cats with a recent history of URT disease, cats from single cat households, cats from multiple-cat households, and cats from a colony.


RESULTS
Bordetella bronchiseptica was recovered from 7 cats (5 from pharyngeal samples and 2 from nasal samples). Five of the 7 cats appeared to be healthy at the time of sampling, whilst 2 showed clinical signs of URT disease. Six of the 7 culture-positive cats were from a cat colony. The prevalence of B. bronchiseptica in healthy cats sampled was 7% and in cats with URT disease was 8%.


CONCLUSIONS
This study confirms that B. bronchiseptica infection is present, but the prevalence of infection is low, in both healthy cats and in cats with URT disease attended by the Massey University Veterinary Teaching Hospital. It is unlikely that B. bronchiseptica infection is a frequent cause of feline URT disease of cats in this region.
