Detection of Pyrazinamide-Resistant Mycobacteriumtuberculosis by PCR-SSCP of pncA Gene

open access: yesTuberculosis and Respiratory Diseases, 1998
Background : Recently the incidence of tuberculosis is increasing in many countries and control of the disease is further threatened by the emergence of multi-drug resistant tuberculosis. So rapid detection of drug resistance is very important. Pyrazinamide (PZA) is a first-line chemotherapeutic agent for tuberculosis.
