In Vitro Susceptibility of Mycobacterium tuberculosis Clinical Isolates to Garenoxacin and DA-7867

Abstract
The in vitro activities of DA-7867, a novel oxazolidinone, and garenoxacin (BMS-284756) were compared to those of linezolid in 67 susceptible and drug-resistant clinical isolates of Mycobacterium tuberculosis . DA-7867 was the most active drug with an MIC 90 of 0.125 μg/ml, compared to the MIC 90 s of 4 μg/ml of garenoxacin and 2 μg/ml of linezolid.
