Abstract:
A 17-wk-old male Rottweiler puppy was found dead 2 d after being presented with coughing and lethargy. Gross and histopathologic findings were consistent with fibrinosuppurative bronchopneumonia, and Pasteurella canis was isolated on culture of the lung. Mycoplasma cynos was identified by PCR testing of the lung in this case and may have contributed to the development of the pneumonia. P. canis is not a commonly recognized cause of canine bronchopneumonia but likely has a role in the canine respiratory disease complex. P canis is a known cause of pneumonia in other species with similar histologic findings, including humans.
