Drug resistance analysis on 694 strains of Acinetobacter baumannii

Objective To understand the clinical distribution and drug resistance characteristics of Acinetobacter baumannii in Dalian Municipal Friendship Hospital in order to provide reference for the clinical treatment of Acinetobacter baumannii infection.Method A retrospective statistical analysis was performed on the clinical distribution and drug resistance results of 694 Acinetobacter baumannii isolated from inpatient samples between 2007 and 2009.Result 112 strains of Acinetobacter baumannii(7.1%) were detected in 2007,210 strains(11.3%) in 2008,and 372 strains in 2009.Detection rate of Acinetobacter baumannii was 88.7% in sputum specimens,which was the highest among all kinds of specimens.13 kinds of antibiotics were used in antibiotic susceptibility test.The sensitivity of Acinetobacter baumannii to meropenemin was the highest,followed by cefoperazone/sulbactam.Conclusion Detection rate of Acinetobacter baumannii is increasing year by year,so is its drug resistance rate.
