ABSTRACT
BACKGROUND:
BACTEC MGIT 960 system(Becton Dickinson, USA; MGIT 960) is a fully automated, noninvasive culture system for mycobacteria, which has been regarded as a sensitive and least labor-intensive method. This study was purposed to evaluate the performance of MGIT 960 compared to BACTEC 460 TB radiometric system(Becton Dickinson, USA; BACTEC 460) and Ogawa media.METHODS:
A total of 1,067 clinical specimens submitted from April to June in 1999 was cultured for acid fast bacilli(AFB). All specimens were digested, decontaminated by the 6% sodium hydroxide(final concentration of 1.5%) and 0.5% N-acetyl-L-cysteine method. All specimens were inoculated into three kinds of media a MGIT, a BACTEC 12B, and an Ogawa medium. The AFB recovered from cultures were identified to M. tuberculosis complex and MOTT by NAP test.RESULTS:
Of 106 isolates of M. tuberculosis recovered from all culture systems, 101(95.3 %) were detected in the MGIT 960, 95(89.6%) in the BACTEC 460 and 76(71.7%) on Ogawa media. MGIT 960 plus Ogawa media detected 104(98.1%) isolates and BACTEC 460 plus Ogawa media recovered 96(90.6%) isolates. The mean time required for detection of M. tuberculosis was 12.7+/-5.8 days with MGIT 960, 16.2+/-7.7 days with BACTEC 460, and 22.8+/-9.5 days with Ogawa media. The contamination rate were 5.1% for MGIT 960, 2.7% for BACTEC 460, and 6.7% for Ogawa media.CONCLUSIONS:
MGIT 960 is a sensitive and rapid method to isolate M. tuberculosis.
