Rifampin susceptibility of ribonucleic acid synthesis in a fragile Saccharomyces cerevisiae mutant.

abstract：:No studies have investigated whether discontinuation of ethambutol (EMB) based on the susceptibility to isoniazid and rifampin as determined by the GenoType MTBDRplus assay would be appropriate. We aimed to determine the feasibility of discontinuing EMB before the end of intensive phase treatment based on the result o...
