Two clinical isolates of Escherichia coli, EC18 and EC21, were non-susceptible (MICs 4-16 mg/L) to cefpirome and cefepime, with marked synergy with clavulanate, yet were susceptible to cefotaxime and ceftazidime (MICs ? 1 mg/L). EC19, from the same patient as EC21, was susceptible to all four cephalosporins. We sought to characterize the molecular basis of resistance in isolates EC18 and EC21.
