Cats residing in or entering rescue shelters and multiple-cat households have the highest risk of exposure, especially if respiratory tract disease has occurred in the environment. A vaccine to prevent disease caused by Bordetella bronchiseptica is available. Studies conducted by the manufacturer indicate that the vaccine can reduce the severity of disease in infected cats. Infection with the single-celled parasite, Giardia lamblia, may be associated with gastrointestinal tract disease of either short or long duration. Diarrhea is the most commonly encountered sign of infection.
