evaluation of gene mutations involved in drug resistance in mycobacterium tuberculosis strains derived from tuberculosis patients in mazandaran, iran, 2013

چکیده
drug resistance (especially multiple drug resistance) in mycobacterium tuberculosis makes global concerns in treatment and control of tuberculosis. rapid diagnosis of drug resistant strains of the bacteria has vital importance in the prognosis of the disease. the aim of this study was to identify the mutations responsible for drug resistance in mycobacterium tuberculosis strains derived from patients with tuberculosis using line probe assay (lpa) method which rapidly detect drug resistant strains and respective mutations. sputum samples from tuberculosis patients were collected and cultured on lowenstein– jensen medium, and then the colonies of mycobacterium tuberculosis from cultures of 54 bacterial positive cases were randomly chosen for dna extraction. bacterial dna was extracted using standard cetyl trimethyl ammonium bromide (ctab) method. in order to identify drug resistant strains and related mutations, lpa method was applied. three subjects out of 54 investigated cases were resistant to quinolone (5.5%), and resistance to kanamycin/ amikacin, streptomycin, rifampin, and isoniazid were observed in 3 (5.5%), 4 (7.4%), 3 (5.5%), and 2 (3.7%) of the mycobacterium tuberculosis strains, respectively. in the present study, 4 cases (7.4%) were detected to be resistant to more than one drug. since lpa is a rapid method that simultaneously detects mutations involved in drug resistance, applying this method in the prediction of drug resistance and selecting appropriate treatment in tuberculosis patients is recommended.

متن کاملA STUDY OF MYCOBACTERIUM TUBERCULOSIS DRUG RESISTANCE IN PULMONARY TUBERCULOSIS
Tuberculosis remains a major public health problem in both developing and developed countries. Drug-resistant tuberculosis is an increasing health problem and serious challenge to tuberculosis (TB) control programs. Information about the susceptibility pattern of Mycobacterium tuberculosis isolates against anti-tuberculosis drugs is an important aspect to TB control. The objectives of the s...
متن کاملMutations in the RpoB Gene of Multidrug-Resistant Mycobacterium Tuberculosis Isolates from Semarang, Indonesia
ABSTRACTTuberculosis is an infectious disease which occurs widely in the world and becomes one of the top 10 causes of death worldwide. Mutations of the RpoB gene cause the resistance of Mycobacterium tuberculosis to rifampicin that contributes to the occurrence of MDR-TB. This study aimed to determine the pattern of rpoB gene polymorphisms in the MDR M. tuberculosis in Semarang, Indonesia. Mos...
متن کاملIsoniazid MIC and KatG Gene Mutations among Mycobacterium tuberculosis Isolates in Northwest of Iran
Objective(s) Isoniazid (INH) is one of the main first line drugs used in treatment of tuberculosis and development of resistance against this compound can result in serious problems in treatment procedures. Resistance to INH is mediated mainly by mutation in KatG gene that is coded for the catalase enzyme. The proportional method for detection of INH-resistance is time consuming due to the slo...
