Activity of linezolid against 3,251 strains of uncommonly isolated gram-positive organisms: Report from the SENTRY antimicrobial surveillance program

Linezolid was tested against 32 species of uncommonly isolated gram-positive organisms (3,251 strains) by reference MIC methods and found to be highly active (MIC,0 range, 0.25 to 2 mu g/ml; MIC90, range, 0.25 to 2 mu g/ml).
