Figure 1: Example of results showing banding patterns and their evaluation obtained with the GenoType MTBDRplus Ver 2.0 assay. Line 1, positive control (Mycobacterium tuberculosis strain, ATCC 27294); line 2, MDR-TB with high-level INH resistance MTB heteroresistant to both RIF and INH with high-level INH resistance; line 3 MTB susceptible to both RIF and INH; line 4, MDR-TB with high-level INH resistance; line 5, MTB RIF resistant and INH susceptible; lines 6–8, MDR-TB with high-level INH resistance; line 9, MTB susceptible to both RIF and INH; line 10, negative control (sterile distilled water). MDR-TB: Multidrug-resistant tuberculosis, INH: Isoniazid, RIF: Rifampicin, MTB: Mycobacterium tuberculosis
