[Etiology of nonspecific diseases of the respiratory organs in patients with pulmonary tuberculosis].

Microbiological investigation of sputum and serological investigation of blood serum from patients with pulmonary tuberculosis complicated by secondary infections were performed to determine etiology of the concomitant non-specific diseases of the respiratory organs. It was shown that the main etiological agents causing the concomitant inflammatory diseases were Str. pneumoniae in the new cases of tuberculosis and Str. alpha-haemolyticus in the patients with relapsing tuberculosis. Sensitivity to the broad-spectrum antibiotics was stated in 70 per cent of the strains isolated from the new cases of tuberculosis and in 50 per cent of the strains isolated from the patients with relapsing tuberculosis. The isolates were mainly resistant to tetracycline, streptomycin and kanamycin.
