Abstract
Objective To investigate the clinical distribution and drug resistance characteristics of Stenotrophomonas maltophilia (S.maltophilia)strains,aiming to provide guidelines for the clinical prevention and treatment of S.maltophilia and control of nosocomial infection.Methods A total of 1 40 S.maltophilia strains isolated from various clinical specimens from July 201 1 to June 201 4 were cultured,identified and tested for drug sensitivity by using Microscan microbial identification and subjected to antibiotic resistance analysis. The data analysis was performed by WHONET V5.5.Results Approximately 80.0% of S.maltophilia strains were detected from the respiratory tract phlegm samples,mainly distributed in intensive care unit (ICU) (35.7%),neurosurgery department (1 2.9%),and respiratory department (1 1 .4%).The overall resistance rate of 1 40 isolated strains to compound sulfamethoxazole was 7.1 %,24.3% for levfloxacin,79.3% for ce-phradine and 71 .4% for ticarcillin/clavulanate.Conclusions Most of the S.maltophilia were isolated from ICU and neurosurgery department in our hospital,dominantly from respiratory tract infection.S.maltophilia stains had relatively high sensitivity to compound sulfamethoxazole and levloxacin,and were relatively highly resistant to cephradine and ticarcillin/clavulanate.关键词
