Comparative In Vitro Activities of Ceftaroline and Tedizolid against Clinical Strains of Staphylococcus aureus and Enterococcus: Results from the China Antimicrobial Surveillance Network (CHINET) in 2018.

Abstract

The in vitro activities of ceftaroline and tedizolid were compared against Staphylococcus aureus, Enterococcus faecalis, and Enterococcus faecium clinical isolates collected from the China Antimicrobial Surveillance Network. Ceftaroline demonstrated potent activity against S. aureus isolates (MIC50/90, ≤0.25/1 mg/liter). Tedizolid was also highly active against S. aureus (MIC50/90, 0.25/0.5 mg/liter) and Enterococcus (MIC50/90, 0.5/0.5 mg/liter) isolates. Our results support the clinical usefulness of ceftaroline and tedizolid in treating Gram-positive infections.
