Vicissitudes of Antimicrobial Resistance Profile of Burkholderia cepacia Isolated from Clinical Specimens / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the antimicrobial resistance profile of Burkholderia cepacia isolated from clinical specimens in past 3 years.METHODS The B.cepacia strains were isolated from various clinical specimens by routine method from Jan 2004 to Dec 2006.In our hosptial the identification and antimicrobiol susceptibility test were determined by VITEK-32 Full Automated Microbiology Analyzer.RESULTS A total of 126 strains of B.cepacia were isolated.From them 75.14% and 15.08% of isolates were from lower respiatory tract and blood.All isolates were resistant to aminoglycosides,ampicillin,ampicillin/sulbactam,amoxicillin/CLAB,cefazolin,nitrofurantoin,and imipenem.The antibiotic resistant rates of the isolates to SMZ+TMP,cefepime,cefoperazone/sulbactam,meropenem,ceftazidime and piperacillin/tazobactam were 5.10%,16.99%,39.18%,39.61,39.65% and 48.12%,respectively.CONCLUSIONS The detection and antimicrobial resistance of the isolates of B.cepacia are increasing gradually.Multidrug resistance in the isolates of B.cepacia is serious.
