Using cultivation and a culture–independent molecular method, the aim of this study was to assess the bacteriological incidence in the bronchoalveolar lavage fluid (BALF) of pneumonia patients. The study findings suggested that M. catarrhalis was more frequently detected in pneumonia patients with moderate or severe emphysema than in those with no or mild emphysematous changes on chest computed tomography (CT). Further analyses revealed that M. catarrhalis might play a major role in patients with pneumonia complicating severe pulmonary emphysema.
