目的:了解宁波地区嗜麦芽窄食单胞菌的感染分布和耐药情况,提高临床对嗜麦芽窄食单胞菌的防治水平。方法:采用梅里埃VITEK-2全自动细菌鉴定药敏系统及纸片扩散法(K-B法)测定229株嗜麦芽窄食单胞菌对15种抗菌药物的敏感性。结果:229株嗜麦芽窄食单胞菌主要来源于下呼吸道标本,占71.2%,在临床病区分布居前四位的依次为ICU,呼吸科,神经外科,肿瘤外科。229株嗜麦芽窄食单胞菌对舒普深、左氧氟沙星、复方新诺明、多黏菌素B、米诺环素均显示>80%的敏感。结论:嗜麦芽窄食单胞菌医院感染已十分严重,它的首选药物为舒普深、左氧氟沙星、复方新诺明、米诺环素。
Objective: To understand the distribution and drug resistance of Stenotrophomonas maltophilia in Ningbo and to improve the prevention and treatment of Stenotrophomonas maltophilia. Methods: The sensitivity of 229 strains of Stenotrophomonas maltophilia to 15 kinds of antibacterial drugs was determined by the automatic biosensor system of VITEK-2 and K-B method. Results: Totally 229 strains of Stenotrophomonas maltophilia originated from the lower respiratory tract, accounting for 71.2%. The top 4 places in the clinical ward were ICU, respiratory department, neurosurgery and oncology. 229 Stenotrophomonas maltophilia showed> 80% sensitivity to Shu Pu Shen, levofloxacin, cotrimoxazole, polymyxin B and minocycline. Conclusion: Stenotrophomonas maltophilia nosocomial infection has been very serious, its preferred drugs are Shu Pushen, levofloxacin, cotrimoxazole, minocycline.
