The GenoType MTBDRplus assay/PCR-sequencing data showed that all pansusceptible strains (n = 50) were susceptible to RIF (Table 2) and INH as they yielded wild-type patterns for rpoB, katG and inhA. All MDR-TB strains were resistant to RIF based on GenoType MTBDRplus assay/PCR-sequencing data as they exhibited an rpoB mutation. The gene discussed is INHA; the disease is tuberculosis.
