Rapid detection of multidrug-resistant Mycobacterium tuberculosis using the malachite green decolourisation assay
Early detection of drug resistance in Mycobacterium tuberculosis isolates allows for earlier and more effective treatment of patients. The aim of this study was to investigate the performance of the malachite green decolourisation assay (MGDA) in detecting isoniazid (INH) and rifampicin (RIF) resistance in M. tuberculosis clinical isolates. Fifty M. tuberculosis isolates, including 19 multidrug...
متن کاملComparison of BACTEC MGIT 960 system and BACTEC 460 TB system for growth and detection of Mycobacteria from clinical specimens.
This study was carried out to compare the performance of BACTEC MGIT 960 with the BACTEC 460 TB for growth and detection of Mycobacteria from human clinical specimens. The BACTEC MGIT 960 instrument is a fully automated system that utilizes MGIT tubes containing an oxygen sensor embedded in silicon at the bottom and filled with 7 mL of modified Middlebrook 7H9 broth. Identical samples were inoc...
متن کاملColorimetric detection of multidrug-resistant or extensively drug-resistant tuberculosis by use of malachite green indicator dye.
The malachite green microtube (MGMT) susceptibility assay was performed directly on sputum specimens (n = 80) and indirectly on Mycobacterium tuberculosis clinical isolates (n = 60). The technique is based on the malachite green dye, which changes color in response to M. tuberculosis growth. The MGMT assay is simple and rapid and does not require expensive instruments.
متن کاملComparison of the MB/BacT and BACTEC 460 TB systems.
We have read the recent report by Brunello et al. (1) about a comparative study between the MB/BacT and the BACTEC 460 TB systems for recovery of mycobacteria. We have carried out a similar study with 500 clinical specimens (89% respiratory and 24.3% nonrespiratory), and we would like to make some comments. First, like Brunello et al., we did not find any statistically significant differences b...
متن کاملComparison of recoveries of mycobacterium tuberculosis using the automated BACTEC MGIT 960 system, the BACTEC 460 TB system, and Löwenstein-Jensen medium.
Using two different liquid media and one conventional solid medium, a total of 57 mycobacterial isolates (Mycobacterium tuberculosis, n = 55; nontuberculous mycobacteria, n = 2) were recovered from 377 clinical specimens. The rates of recovery of M. tuberculosis were 96. 4% with the BACTEC MGIT 960 liquid medium, 92.7% with BACTEC 12B liquid medium, and 81.8% with the Löwenstein-Jensen (LJ) med...
