چکیده
INTRODUCTION: This study aimed to evaluate a new commercial kit, Kit SIRE Nitratase-PlastLabor, for testing the drug susceptibility of clinical Mycobacterium tuberculosis isolates. METHODS: The accuracy of the Kit SIRE Nitratase was evaluated by examining the susceptibility (streptomycin, isoniazid, rifampicin, and ethambutol) of 40 M. tuberculosis isolates, using the proportion method with Lowenstein-Jensen medium or the BACTEC MGIT 960 system. RESULTS: The detection accuracy for streptomycin, isoniazid, rifampicin, and ethambutol was 95%, 97.5%, 100%, and 80%, respectively. CONCLUSIONS: The exceptional accuracy demonstrated by Kit SIRE Nitratase for isoniazid and rifampicin makes the kit an attractive option for screening M. tuberculosis strain resistance.

We evaluated the performance of the DR. TBDR/NTM IVD kit, which was designed to detect Mycobacterium tuberculosis, rifampin-resistant M. tuberculosis, and nontuberculous mycobacteria, for detecting 110 positive and 50 negative cultures in Mycobacterium Growth Indicator Tubes. The accuracy rate of this kit for identification of Mycobacterium species was 95.5% (105/110).
