An 8 year-old cow showing severe dyspnea and nasal mucosal necrosis immediately after parturition was subjected to pathological examination. The principal lesions were fibrinonecrotic rhinitis, necrolic bronchopneumonia and renal infarction. Fusobacterium necrophorum biotype A and Arcanobacterium pyogenes antigens were detected in the nasal and pulmonary lesions. These results suggest that the lesions were caused by a concurrent infection of the detected bacteria and that the pulmonary lesions were caused by the aspiration of infectious materials from the nasal ones. Mucosal coagulative necroses observed as the initial lesions in rhinitis were frequently associated with multiple thrombosis. The findings might suggest that thrombosis played an important role in the development of the nasal lesions.
