Abstract:
Objective To understand the specimen sources,clinical characteristics,and antimicrobial resistance of Burkholderia cepacia (B .cepacia )isolated from infected patients in intensive care unit(ICU),so as to provide reference for guiding rational use of antimicrobial agents.Methods Clinical data of patients with B .cepacia infec-tion in an ICU between 2011 and 2014 were analyzed retrospectively,antimicrobial resistance of strains was ana-lyzed.Results A total of 267 B .cepacia strains were isolated,the major specimen sources were sputum (80.15%, n=214),blood(14.23%,n =38),and urine(3.37%,n =9).Antimicrobial susceptibility testing results revealed that B .cepacia had multiple resistance,and was naturally resistant to multiple clinically used antimicrobial agents, such as ampicillin,cefazolin,ampicillin/sulbactam,nitrofurantoin,and cefuroxime,resistant rates were all 100%;resistant rates to ceftazidime and levofloxacin were 4.12% and 3.00% respectively;resistant rate to compound sulfa-methoxazole had increased tendency(χ2 =5.885,P =0.015).Conclusion Isolation of B .cepacia in ICU increased year by year,antimicrobial resistance is serious,management and targeted monitoring of prevention and control of healthcare-associated infection should be strengthened,antimicrobial agents should be chosen according to antimi-crobial susceptibility testing results.
