For MM2201 - Bordetella bronchiseptica

Bordetella bronchiseptica is Gram-negative rod, motile (peritrichous flagella); does not use carbohydrate. It grows well on MacConkey agar. It shows rapid urease production (4 hours) on Christensen's urea slant. Rarely found in humans, however can cause pertussis-like symptoms in immunocompetent hosts; in immunocompromised hosts, illness can range in severity from mild respiratory symptoms to pneumonia; carrier state may exist. The disease is tranfered from person to person through coughing and the generation of infectious droplets. It can also be transmitted from infected animals to humans by infected aerosols, probably droplets.
Bordetella bronchiseptica is usually a cause of pneumonia, otitis media, and other respiratory infections in animals (e.g. dogs, cats, swine, etc.).
