Mutational analysis of the rpoB gene of Mycobacterium Tuberculosis Strains

THE JOURNAL OF MICROBIOLOGY AND MOLECULAR GENETICS
Tuberculosis is an endemic.  The menace of tuberculosis has affected one third of human population. Pakistan ranks 6th among high burden TB countries and 4th among the countries with highest rate of MDR-TB. Mycobacterium tuberculosis, the etiological agent of tuberculosis, has an incubation time of 8 weeks.
