Molecular Characterization And Comparison Of Multi Drug Resistant Strains Of Mycobacterium Tuberculosis By Phenotypic And Genotypic Method

Introduction: Drug resistant tuberculosis is a signifi cant threat to tuberculosis control because only a few effective drugs are available against M. tuberculosis. The aims of this study were to compare multi drug resistant (MDR) strains of tuberculosis by phenotypic and genotypic method and determine type, location and frequency of rpoB and KatG gene mutations.
