|The case history of a domestic shorthair cat with acute tracheobronchitis is described. The most important clinical sign was a productive cough. A pure culture of Bordetella bronchiseptica was isolated on culture of an airway wash sample.
While antibiotic sensitivity testing showed the bacteria to be sensitive to enrofloxacin, treatment for 18 days with this medication failed to resolve the clinical signs and did not clear the bacteria from the lower respiratory tract.
Antibiotic therapy was changed to trimethoprim-sulfadiazine, which appeared to lead to resolution of the clinical signs, as well as elimination of the bacteria from the respiratory tract. B bronchiseptica appears to spread easily and quickly among cats and seroprevalence appears to be high.
Practitioners should consider it in the differential diagnosis of bronchopulmonary disease in the cat, especially in multi-cat households and catteries. Preliminary work on a vaccine appears promising, although the canine vaccines are currently being used on a limited basis in cats at risk.
