Abstract

This study aimed to provide information that bedaquilline is significantly effective for treatment of totally drug resistant (TDR) Mycobacterium tuberculosis that shows resistant to all first- and second-line drugs-using an innovative disc Agarose channel (DAC) system. Time-lapse images of single Bacterial cells under culture conditions with different concentrations of bedaquiline were analysed by image processing software to determine minimum inhibitory concentrations (MICs). Bedaquiline inhibited the growth of TDR M. tuberculosis strains, with MIC values ranging from 0.125 to 0.5 mg/L. The results of the present study demonstrate that bedaquiline, newly approved by the United States Food and Drug Administration (FDA), may offer therapeutic solutions for TDR-TB.
