Abstract excerpt
BACKGROUND: Ceftaroline (PPI-0903M, T-91825) is a novel cephalosporin, administered as an N-phosphono prodrug. We investigated its in vitro activity and resistance selection potential. METHODS: MICs were determined by CLSI agar dilution, but with varied inocula. Mutant selection was investigated in single- and multi-step procedures. RESULTS: MICs for methicillin-resistant Staphylococcus aureus (MRSA) were 0.5-2...
