Prevalence of hospital acquired Burkholderia cepacia infection and its antimicrobial susceptibility in a Chinese hospital

ABSTRACT

This study aimed to investigate antimicrobial susceptibility of hospital acquired Burkholderia cepacia infection in Shanxi [China] during August 2009 and December 2012. To characterize an emerging nocosomial infection. The medical records of 112 patients that were tested positive for B. cepacia were retrospectively analyzed. The K-B disk diffusion method was used to determine the drug susceptibility of the isolated strains. A hundred and fifty strains of B. cepacia were isolated from 112 patients. The sensitivity rates of B. cepacia to meropenem, imipenem, cotrimoxazole, minocycline and ceftazidime were 65.7%, 14.3%, 76.0%, 68.1% and 74.1%, respectively. All patients suffered from more than two underlying diseases, 89 [79.5%] from another bacterial infection and 92 [82.1%] with indwelling catheter. All patients were given antibiotics, including 62 patients that received carbapenem antibiotics. The average duration of hospitalization before detection of B. cepacia was 31+/-24 days, after which 65 patients [58.0%] improved, 22 [19.0%] died, 8 [7.1%] quit the therapy, and 17 [15.2%] were discharged after full recovery. The prevalence of hospital acquired B. cepacia infection and drug-resistance in the hospital is reported and risk factor exploration requires further study
