Abstract:
Most first-line anti-tuberculosis drugs have less in vitro activity against atypical mycobacteria. Loop-mediated isothermal amplification (LAMP) was used for the rapid diagnosis of mycobacterial species. The sensitivity of LAMP was 96.1% (49/51) in smear-positive and culture-positive sputum samples and 85.0% (17/20) in smear-negative and culture-positive samples. Of the 77 total LAMP-positive samples, 75 (97.4%) were identified as Mycobacterium tuberculosis and 2 (2.6%) as M. intracellulare. One of the M. intracellulare-infected cases was identified in a patient with suspected mycobacteriosis and another was found in a follow-up patient.
