摘要目的加强医院感染的综合防治，提高医院感染的认识，全面了解发生医院感染的菌群及耐药趋势，减少医院感染的发生。 方法对集中在三周内发生同一种细菌引起的医院感染的病人采用法国梅里埃API 20E和美国德灵Micro Scan鉴定系统及K-B法药敏试验进行细菌的鉴定与药敏试验。 结果经鉴定，这9例病人是嗜麦芽黄单胞菌引起的医院感染, 嗜麦芽黄单胞菌分别对庆大霉素、阿米卡星、环丙沙星、妥布霉素100%敏感，而对氨曲南、亚胺培南100%耐药。结论嗜麦芽黄单胞菌是引起医院感染的重要细菌。

    The Analysis Survey Of Nine Cases Nosocomial Infection

    [ Abstract ] Objective to strengthen the synthetic prevention and cure from nosocomial infection, to increase acquaintance with nosocomial infection, reduce the possibility of nosocomial infection. MethodTo authenticate carefully the patients who have caught the nosocomial infection causing by the same bacteria within three weeks with the micro scan appraise systems of the France Bio Merieux API 20E and the USA Dade Behring. And test them by the K-B Medicine Susceptibility.ResultThrough the appraise, these nine patients were proved that their nosocomial infection was caused by Xanthomonas maltophilia. Xanthomonas maltophilia is allergic to Gentamicin, Amikacin, Ciprofloxain and Tobramvcin without fail, but resists Aztreonam and Imipenem without fail. ConclusionXanthomonas maltophilia is an important bacteria causing nosocomial infection. ......
