Postantibiotic Effect of Ceftobiprole against 12 Gram-Positive Organisms

The in vitro postantibiotic effects (PAEs), postantibiotic sub-MIC effects (PA-SMEs), and sub-MIC effects of ceftobiprole were determined for 12 gram-positive organisms. Pneumococcal, staphylococcal, and enterococcal PAEs were 1.4 to 3.1 h, 0 to 1.8 h, and 0 to 0.9 h, respectively. The PA-SMEs (0.4 times the MIC) for pneumococci, staphylococci, and enterococci were 4.8 to >10.3 h, 1.5 to 9.6 h, and 3.8 to >10.7 h, respectively.
