Figure 1: (a) Sensitive strain: All Wild-Type Bands for Rifampicin (rpo B) and Isoniazid (inhA and katG) present (b) Strain resistant to both Rifampicin and Isoniazid (Multidrug resistant): rpo B Wild-Type Band (WT8) absent and corresponding mutation (MUT3) present. katG Wild-Type 1 (WT) absent and corresponding (MUT 1) present. (c) Strain resistant to both Rifampicin and Isoniazid (Multidrug resistant): rpo B Wild-Type Band (WT8) absent and corresponding mutation (MUT3) present. katG Wild-Type 1(WT) absent and corresponding (MUT 1) present. inhA Wild-Type Band(WT1) absent and corresponding mutation(MUT1) present. (d) Heteroresistance: All rpo B Wild-Type Bands present and mutation bands MUT2B and MUT3 present, which refl ects the presence of both sensitive and resistant strains in the same sample (patient). Proportion method showed resistance to Rifampicin
