چکیده

We have developed a Real-Time PCR assay to detect M. tuberculosis using the iCycler iQ detection system by TaqMan assay directly on the clinical specimen. A total of 513 clinical samples were taken from patients with suspected tuberculosis and other patients that had an active mycobacterial infection, as well as patients with diagnosed tuberculosis who were receiving antitubercular therapy. The sensitivity and specificity of this assay, 10% and 100%, respectively, were compared to those of conventional microbiological methods.

Comparison 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...

Evaluation of BACTEC MGIT 960 system for the second-line drugs susceptibility testing of Mycobacterium tuberculosis in China.

When the performance of the BACTEC MGIT 960 system was evaluated with the traditional proportion method (PM) on 321 clinical isolates of Mycobacterium tuberculosis from China, concordance values were 98.44% capreomycin, 98.75% kanamycin, 98.75% ofloxacin and 94.08% ethionamide. The turnaround time with BACTEC MGIT 960 system (7.5±1.8 days) was significantly shorter than with PM (28 days or 42 d...

Evaluation of the BACTEC MGIT 960 and the MB/BacT systems for recovery of mycobacteria from clinical specimens and for species identification by DNA AccuProbe.

A total of 120 mycobacterial isolates were recovered from 1,068 clinical specimens. Of these, 82.5% were in MGIT 960, 83.3% were in MB/BacT, 80% were in BACTEC 460, and 70% were on Löwenstein-Jensen medium. Mean times to detection of Mycobacterium tuberculosis (n = 96) were significantly shorter with MGIT 960 (12.6 days, P = 0.003) and BACTEC 460 (11.8 days, P < 0.001) than with MB/BacT (15.9 d...

Rapid identification of Mycobacterium tuberculosis in BACTEC MGIT960 cultures by in-house loop-medicated isothermal amplification.

Definitive diagnosis of tuberculosis (TB) by conventional culture, followed by bacterial identification based on biochemical tests is time-consuming and tedious. Simple loop-mediated isothermal amplification (LAMP) specific for Mycobacterium tuberculosis complex, targeting the M. tuberculosis 16S ribosomal RNA gene, termed TB-LAMP, was evaluated as an alternative for rapid culture confirmati...

Comparative evaluation of BACTEC MGIT 960 with BACTEC 9000 MB and LJ for isolation of mycobacteria in The Gambia.

BACKGROUND The BACTEC MGIT 960 was evaluated and compared with BACTEC 9000 MB and Lowenstein-Jensen medium for recovery rate of mycobacteria, time to detection, and contamination rate. METHODOLOGY 147 sputum samples obtained from patients with suspicion of tuberculosis were processed and inoculated into BACTEC MGIT 960, BACTEC 9000 MB and Lowenstein-Jensen medium using standardized procedures...
