Abstract:
:Mycobacterium tuberculosis is naturally resistant to clarithromycin (CLR). The genes Rv3197A (whiB7) and Rv1988 (ermMT) have been shown to be involved in the resistant phenotype. In this study, a CLR-susceptible M. tuberculosis clinical strain was identified, designated as DS3214, and the nucleotide sequences and expression profiles of whiB7 and ermMT were investigated. The results revealed that strain DS3214 contained a one nucleotide deletion in whiB7, leading to a truncated peptide. Expression of whiB7 was low, whereas comparable expression of ermMT was determined compared with the reference strain M. tuberculosis H37Rv. Overexpression of the mutant whiB7 in M. tuberculosis H37Ra did not increase the minimum inhibitory concentration (MIC) to CLR or kanamycin, indicating the defect of the mutant WhiB7. The CLR-susceptible M. tuberculosis clinical strain, whose whiB7 is naturally mutated, was first described in this study and whiB7 has been shown to play a role in the CLR-susceptible phenotype.
