Molecular diagnostic techniques are crucial parts of the World Health Organization’s new tuberculosis control strategy. This study aims to identify Mycobacterium tuberculosis and rifampin resistance in pulmonary and extra-pulmonary clinical specimens using the Gene Xpert MTB/RIF assay. Methods: The study was carried out on 220 specimens from pulmonary and extra-pulmonary TB patients that were sent to the Kavosh Laboratory in Gorgan (Iran) during 2018-20. The Gene Xpert MTB / RIF method was applied to detect M. tuberculosis and rifampin resistance. Results: Of 220 specimens, 15 (6.81%) were found to be positive, four (26.6%) of which were related to pulmonary and 11(73.3%) to extra-pulmonary specimens. None of the positive samples was resitant to rifampin according to assay. Conclusion: Our findings demonstrate that the Gene Xpert MTB/RIF is able to accurately detect M. tuberculosis in pulmonary and extra-pulmonary specimens. The accurate and early diagnosis of TB infection allows timely therapeutic intervention, which is beneficial not only for the patient but also for possible contacts.http://mlj.goums.ac.ir/article-1-1314-en.htmlmycobacterium tuberculosistuberculosis multidrug-resistantrifampin |
