A total of 248 Gram-positive isolates from cancer patients were tested for in-vitro susceptibility to tedizolid and 3 comparator agents using CLSI broth microdilution methodology. Tedizolid inhibited 97% of isolates at ≤0.5μg/ml. It was active against all Gram-positive species and consistently had 8 fold lower MICs than linezolid, although based on % susceptibility using CLSI breakpoints, most isolates were also susceptible to the comparators. Tedizolid was active against MRSA isolates with vancomycin MICs of ≥1.0μg/ml.
