[Evaluation of bronchoalveolar lavage in the microbiological diagnosis of pneumonia in patients at risk].

Bronchoalveolar washout was performed in 130 patients with pneumonia during a period of 28 months. Microbiological investigation involved common bacteria, Legionella, fungi, viruses (Cytomegalovirus, herpes, RSV), Mycobacterium, and Pneumocystis carinii.
