چکیده مقاله:
Background and Aim:Nontuberculous mycobacteria(NTM) can be a cause of a variety of diseases that can not be distinguished from tuberculosis (TB) and is a diagnostic and therapeutic challenge. The purpose of this study was to isolate Nontuberculous mycobacteria from patients suspected to having pulmonary tuberculosis referring to Tehran regional tuberculosis laboratory.Methods:To identify NTM isolated from patients suspected of pulmonary tuberculosis at the species level, phenotypic tests including the method of Petroff method (NaOH 2%) as well as biochemical test were applied on the Loon Stein Johnson media. Also from colonies the DNA was extracted and PCR was performed for interested genes.Results:Overall 62 NTM strains were isolated from studied clinical samples were taken from TB suspected patients. Mycobacterium simiae(22.5%) was the most common isolated NTM followed by Mycobacterium fortuitum (16.1%), Mycobacterium kansasii (12.9%) and M. avium complex (6.4%).Conclusion:Our data showed that a significant number of tuberculosis cases were caused by NTM strains, among which Mycobacterium simiae has the highest prevalence. M. simiae can cause the same illness as tuberculosis, which is a serious problem for public health and attracts the attention of health officials, physicians and microbiologists.
