Streptococcus bovis infections in pigeons

Abstract

Streptococcus bovis infection was diagnosed in pigeons from 20 lofts submitted for post mortem investigation. Clinical signs were very variable and ranged from hyperacute death to chronic lameness with arthritis. Lesions were generally unspecific except for single cases of muscle necrosis with purulent myositis. Histological examinations demonstrated the septicaemic nature of the infections. Intravenous inoculations of S. bovis resulted in prostration, long lasting loss of weight and polyuria. Microscopically purulent hepatitis and nephritis were the most characteristic lesions. After oral inoculation no clinical signs were seen.
