Antibiotic Sensitivity of Stenotrophomonas maltophilia Isolated from Clinical Patients / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To study the antibiotic resistance features of Stenotrophomonas maltophilia isolated clinically for correctly choosing antibiotic in clinics. METHODS The samples of patients with lower respiratory tract inflection between Jan 2006 and Apr 2008 were collected.A total of 160 strains of S.maltophilia had been tested for analyzing drug susceptibility. RESULTS The isolated rate of S.maltophilia was high in sputum samples then in urine and blood.Drug-sensitive test showed that:the resistance rate of S.maltophilia to ticarcillin / clavulanic Acid,levofloxacin,cefepime,piperacillin,and ceftazidime were 0.63%,12.50%,18.13%,18.75% and 21.35%,respectively. CONCLUSIONS S.maltophilia mainly causes respiratory tract infection in patients,showing serious drug resistance.In treating S.maltophilia infection,antimicrobial drugs should be selected according to the results of antimicrobial susceptibility test.
