| ABSTRACT Objective: To provide basis for clinical rational use of antibacterial by studying the source, distribution and drug resistance of Stenotropomonas maltophilia in Lishui Central Hospital. Methods:367 strains of S. maltophilia were collected from January 20009 to December 2012. Identified the bacteria strains with VITEK 2 COMPACT instrument.And the drug resistance test adapted K-B test.Results: S.maltophilia were mainly isolated from sputum sample, accounting for 86.6%. The clinical distribution of ICU was the highest in the hospital,accounted for 38.4%. The resistance rate of S.maltophiliato minocycline, levofloxacin, trimethoprim sulfamethoxazole and cefoperazone/sulbactam were 6.6%,8.8%,10.4% and 9.8%. Conclusion:The S.maltophilia were mainly isolated from specimen of sputum in ICU, neurosurgery department and respiratory medicine department. The organism was inherently resistant to most antibacterial agents, but less resistant to minocycline, levofloxacin、trimethoprim sulfamethoxazole and cefoperazone sulbactam.The clinician should choose suitable antibiotics based on the results of drug sensitivity tests. |
