In Vitro Activity of Oxazolidinone against Nontuberculous Mycobacteria, Including Macrolide-Resistant Clinical Isolates.

We evaluated the in vitro activities of oxazolidinone antibiotics including linezolid, sutezolid, and delpazolid against clinical nontuberculous mycobacteria isolates. Regardless of macrolide resistance, for M. avium, M. intracellulare, and M. kansasii, sutezolid showed the lowest minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) value among oxazolidinone antibiotics. However, for M. abscessus, M. massiliense, the MIC and MBC values for all oxazolidinone antibiotics showed similar values. Oxazolidinone antibiotics warrant further investigation as potential antibiotics.
