M. tuberculosis Central Asian Strain 1 MDR isolates have more mutations in rpoB and katG genes compared with other genotypes.

Abstract excerpt

Pakistan ranks eighth globally among TB burden countries, with a MDR rate of 2-5%. The most prevalent MTB genotype is Central Asian Strain1 (CAS1) followed by the Beijing genogroup. We investigated common mutations in multidrug resistance encoding genes rpoB, katG and inhA of CAS1 and Beijing strains using DNA sequencing and fluorescent resonance energy transfer (FRET) probe based real-time PCR methods. 30 CAS1,...
