[Role of PCR analysis in complex bacteriological studies in phthisiology].

The study was undertaken to assess the role of polymerase chain reaction (PCR) analysis in complex bacteriological studies in diagnosing pulmonary tuberculosis in 197 patients by bacterioscopy, inoculation, and PCR. It was shown that in addition to conventional bacteriological methods, PCR might be used as an additional laboratory study in making a diagnosis in patients with restrictive pulmonary tuberculosis. A combination of cultural inoculation and PCR analysis enhances the sensitivity of bacteriological diagnosis and reduces its duration in oligo- and abacillary patients with tuberculosis. PCR analysis enhances the efficiency of laboratory control over antituberculous chemotherapy.
