[The nonspecific microflora of patients with newly detected active pulmonary tuberculosis complicated by bronchial obstruction].

Eighty-five new cases of active pulmonary tuberculosis and bronchial obstruction in some of them were subjected to bacteriological and serological examinations (quantitative estimation of nonspecific microflora and indirect immunofluorescence test, respectively). Combination of the methods made it possible to show that bronchial obstruction in 52.8 per cent of the cases was due to the presence of nonspecific microflora and that Str. pneumoniae played the leading role in its development in 32.1 per cent of the cases.
