In a retrospective 10-year analysis of 3,536 patient-unique isolates, Acine tobacter baumannii imipenem susceptibility declined from 98.1 (1990) to 64. 1% (2000), and ciprofloxacin susceptibility decreased from 50.5 to 13.1%. I mipenem median zone diameters decreased from 27.7 (1997) to 18.8 mm (2000).
