Summary:The data on the use of the polymerase chain reaction (PCR) with primers INS1 and INS2 for the diagnosis of pulmonary tuberculosis are presented. All stages of PCR are described: from the treatment of biological material to the conditions necessary for carrying PCR and the registration of the results. Simultaneously with this reaction, PCR in a Cobas Amplicor apparatus was carried out and Mycobacterium tuberculosis culture was grown in a liquid medium in an MB/BacT apparatus. The study revealed that the method of PCR in pure M. tuberculosis culture made it possible to detect even the DNA of those cells which formed no colonies on Löwenstein--Jensen medium. The detection of M. tuberculosis in clinical samples (sputum, pleural exudate) taken from 31 patients with different pulmonary pathology showed that in 87.1% of cases diagnostics with the use of PCR carried out in a Cobas Amplicor apparatus and with primers INS1 and INS2 yielded similar results. In patients with pulmonary tuberculosis the results of PCR were positive, while the results of the analysis made with use of an MB/BacT apparatus were negative. The proposed primers INS1 and INS2, the conditions of amplification and detection make up the test system for the detection of mycobacteria of the tuberculosis complex.
