Abstract:
Objective To analyze the clinical distribution and drug resistance of clinically isolated strains of Acinetobacter Bau-mannii(ABA)in our hospital from January 2007 to December 2012 so as to provide the basis for the rational use of antibacterial drugs in clinic.Methods The API microbiological culture and identification system was adopted to conduct the ABA culture,identi-fication and drug susceptibility analysis on the clinical specimens submitted by various clinical department and the drug resistance of the strains was analyzed by using WHONET5.6 software.Results 791 strains of ABA were isolated in the recent 6 years,and the isolating rate of ABA in the pathogenic bacteria was 7.8%;The ABA detection was dominated by the sputum (80.4%)and the throat swab(10.9%)specimens;the distribution of isolated ABA strains were relatively widespread;the infection rates of the pa-tients were higher in ICU (18.8%),cadre wards(17.6%),respiratory medicine department(13.3%)and neurosurgery department (12.3%).During these 6 years,the drug resistance rate of less than 50% included imipenem(IPM)and cefoperazone sodium/sul-bactam,and the resistance rate in most of commonly used antibacterial drugs showed an increasing trend,especially IPM.Conclusion The drug resistance of ABA is more serious and the resistance rate of clinically isolated strains to most of antibacterial drugs in our hospital during 2007- 2012 showed an increasing trend.Dynamically monitoring the ABA distribution and the drug resistance changes conduces to guide the rational use of antibacterial drugs in clinic,prevent the nosocomial infection and reduce the generation of pan-drug resistant strains.
