Liquid media such as the mycobacteria growth indicator tube (MGIT) are widely used for antitubercular drug susceptibility testing (DST) but may cause discordant or invalid results due to ordinary bacterial contamination or mixed mycobacterial colonies. To overcome the drawbacks of DST with MGIT (DSTMGIT), an experiment with a modified method that incorporated a subculture step on the Löwenstein...
OBJECTIVES Pyrazinamide is a key first-line tuberculosis drug. Reliable drug susceptibility testing (DST) data are of clinical importance, but in vitro testing is challenging since the activity of pyrazinamide is pH sensitive. The BACTEC MGIT 960 is considered the principal reference technique, but Wayne's test is an alternative, although it may be difficult to interpret. A further alternative ...
Many laboratories validate DST of the second-line drugs by BACTEC MGIT 960 system. The objective of this study is to evaluate the critical concentration and perform DST for the 2nd line drugs. We evaluated 193 clinical strains of M. tuberculosis isolated from patients in South Korea. Testing the critical concentration of six second-line drugs was performed by MGIT 960 and compared with L-J prop...
The resurgence of tuberculosis along with the increased resistance of Mycobacterium tuberculosis has emphasized the need for timely susceptibility testing for control of the disease. Previous studies have shown that rapid susceptibility testing can be accomplished for isoniazid, ethambutol, and rifampin using the flow cytometric assays. In this study we compared the flow cytometric susceptibili...
