ABSTRACT
INTRODUCTION:
Tuberculosis is still one of the most important health problems in developing countries and increasing drug resistance is the main concern for its treatment. This study was designed to characterize the drug resistant Mycobacterium tuberculosis isolated from patients suffering from pulmonary tuberculosis in northeast of Iran.METHOD:
In this cross-sectional study during 2012-2013, drug susceptibility testing was performed on Mycobacterium tuberculosis isolated in northeast of Iran using proportional method. Epidemiological data concerning these strains were also analyzed.RESULTS:
Among 125 studied isolates, 25 mycobacteria (20%) were diagnosed as nontuberculosis mycobacteria. Among the remaining 100 Mycobacterium tuberculosis isolates, the resistance rates were 7%, 7%, 3%, and 9% against isoniazid, rifampin, ethambutol, and streptomycin, respectively. Four isolates were resistant against both isoniazid and rifampin (MDR tuberculosis). The highest resistance rate was observed among 15-45-year-old patients. The MDR tuberculosis was much more prevalent among those who had previous history of treatment.CONCLUSION:
Considering these findings, DOTS strategy should be emphasized and promptly used in order to prevent further resistance. Regarding the high rate of nontuberculosis mycobacteria, it is recommended that confirmatory tests were performed before any therapeutic decision.
