THE RESULT OF POLYMERASE CHAIN REACTION AND THE VIABILITY OF MYCOBACTERIUM TUBERCULOSIS IN NEWLY DIAGNOSED PATIENTS WITH PULMONARY TUBERCULOSIS
Polymerase chain reaction (PCR) used to detect viable and nonviable mycobacterium tuberculosis (MBT). Bacteriological method has been applied in assessing the viability MBT, detected PCR. The investigations were carried out in the laboratory control of chemotherapy of 72 newly diagnosed patients with pulmonary tuberculosis (TBL). The detection of nonviable MBT was noted with a positive PCR result and no growth of MBT. Thus, nonviable MBT was detected in sputum in 16 (22,22%) out of 72 patients with TBL before treatment, after 2 months of chemotherapy in 37 (51,39%) TBL patients out of 72 examined.
