【摘要】 目的　探讨我院 2 0 0 1年 8月～ 2 0 0 2年 3月显著增多的耐碳青霉烯类鲍曼不动杆菌之间的同源性。　方法用脉冲场凝胶电泳对 7株耐碳青霉烯类鲍曼不动杆菌进行分型 ,明确其是否为同一菌株的克隆。　结果　 7株不动杆菌分为 :A型 2株 ,A1型 2株 ,A2 型 1株。A1型与A2 型之间的相似系数达 94.6% ,它们与A型的相似系数达 84.9% ,其余两株各有独特的PFGE分型。　结论　其中 5株耐碳青霉烯类鲍曼不动杆菌有高度同源性 ,第 5号株极可能是此次院内感染的源头。更多还原

【Abstract】 Objective To investigate the homogeneity of the unusually ever-increasing carbapenm-resistant(CR)Acinetobacer baumannii isolates selected from August 2001 to March 2002 in Shenzhen People’s Hospital.Methods The pulse-field gel electrophoresis(PFGE) was used to type 7 CR Acinetobacter isolates gathered in our hospital,determing whether they derived from the same clone or not.Result 7 isolates was identified to these PFGE types :2 for type A,2 for type A1,1 for type A2.The similarity coeffient between A1 and A2 was 94.6%, 84.9% between A1(A2) and A .The other two isolates showed distinct PFGE types.Conclusion The five CR Acinetobacter baumannii isolates were closely related.The finding highly suggests that V isolate is the source of the nosocomial infection.更多还原
