  • Title: Identification of Mycobacterium tuberculosis by PCR-linked reverse hybridization using specific rpoB oligonucleotide probes.

    Abstract:
    A reverse probe hybridization method using two different Mycobacterium tuberculosis-specific rpoB DNA probes in combination was evaluated for the identification of M. tuberculosis culture isolates. Among the 384 isolates tested, 354 strains were identified as M. tuberculosis, which included 37 rifampin-resistant strains, and 30 were nontuberculous mycobacteria (NTM). This result was in accord with partial rpoB sequence analysis and IS6110 polymerase chain reaction (PCR) results, but not with the results of biochemical testing, which produced two false negative results. Because of its high level of sensitivity and specificity, we suggest that M. tuberculosis-specific rpoB probes immobilized on micro-titer well plates or on other solid matrixes can be used efficiently for the rapid and convenient identification of M. tuberculosis.
