ABSTRACT
Two hundred and seven patients attended Aim Shams Univesity hospital and suspected to have septicemia were included in the study. Blood cultures were performed to all patients. Forty-two [20%] blood cultures were positive, of which 6 isolates [2.9%] were Acinetobacter species. Acinetobacter thus represents 6 of 42 [14.3%] of all bacteremias. Four of the six isolates were A. baumannii [66.7%] and two cases were A. lwoffii [33.3%]. The isolated Acinetobacter strains were resistant to most of antimicrobial agents. Five strains were sensitive to ampicillin/sulbactam and imipenema. Three strains were sensitive to ciprofloxacin and amikacin and only one was sensitive to tobramycin. We recommended the use of ampicillin/sulbactam or imipenem in treatment of Acinetobacter septicemia however, susceptibility testing should be done to select the best antimicrobial drug for therapy
