Report of a case of bronchopneumonia associated with Moraxella boris isolation in a chamois (Rupicapra pyrenaica)

A case of fibrinopurulent bronchopneumonia associated with Moraxella bovis infection in a chamois (Rupicapra pyrenaica) is described. The animal, a 4-month-old female, was referred by the staff warden of the National Game Reserve of Freser-Setcases (Catalonia, north-eastern Spain). The animal was in good general condition and was found 4 h before death. On necropsy the lungs were congested and oedematous, with haemorrhagic areas in the cranial and middle lobes. The microscopic lesions were those of a fibrinopurulent bronchopneumonia. Microbiological study of the samples obtained showed numerous small beta-haemolytic colonies in pure culture, identified as Moraxella (Moraxella) bovis.
