[The value of cytologic and bacteriologic analysis of bronchoscopic specimens with direct microscopy in the diagnosis of pulmonary tuberculosis].

The authors review results for detection of acid-fast bacilli by the method of direct fluorescent microscopy in cytologic specimens obtained by fiberbronchoscopy and in which a granulomatous inflammation was found cytomorphologically. Direct fluorescent microscopy revealed acid-fast bacilli in 30.2% of the specimens.
