The murine thigh model assessed ceftazidime (2 g every 8 h [q8h] HSR) and cefepime (2 g and 1 g q8h HSR). Phenotypes were similar despite possessing OXA-10-like subtypes with differing spectra. Ceftazidime produced >= 1-log(10) killing in all isolates. Cefepime activity was dose dependent and MIC driven. This approach may be useful in assessing the implications of beta-lactamase variants." }
