Analysis of clinical distribution and drug-resistance of 118 strains of Acinetobacter

Objective:To study the distribution and drug resistance of Acinetobacter,in a hospital,so as to provide the reference for rational use of antimicrobial agents.Methats:Acinetobacter isolated from inpatients from January,2005 to January,2009 were identified with ATB Expression microbial identification and drug sensitivity system.Results:A total of 118 strains of Acinetobacter were isolated,most Acinetobacter spp were Acinetobacter baumannii and Acinetobacter calclaceticus,the drug-resistant rate to Ampicillin/sulbactam was 80% respectivdy,drug-resistant rate to Gentamicin,tobramycin,Trimethoprim/sulifa were boty 60%;the drug-resistant rate to Piperacillin,Ticarcillin,Ciprofloxacin,Ceftazidime,Cefepime were both 40%;the drug-resistant rate to Ticarcillin/ca,Piperacillin/tazobacta,Amikacin were both30%;The drug-resistant rate to Imipenem and Meropenem were all low was 5%.Conclusion:Acinetobacter is one of the common bacteria in nosocomial infection.The drug-resistant of Acinetobacter is very serious,it is important to monitor the antimicriobial resistance of Acinetobacter.clinical doctors should use antimicriobial agents rationally and slow down the producing of drug-resistant.
