肿瘤患者细菌检测及耐药性512例分析

目的：了解住院恶性肿瘤患者细菌感染的菌群分布状况及抗生素耐药性。方法：对2005年1月-2006年1月512例肿瘤患者的医院感染进行回顾性调查,进行病原体分析及耐药性监测。结果：医院感染菌株以G-菌为主,占67.70%,其中大肠埃希菌比例最高为25.39%,其次是肺炎克雷伯菌为19.90%;真菌感染占18.16%;G＋菌占15.61%,其中以金黄色葡萄球菌为主（占7.42%）。结论：根据药敏试验合理选择抗生素,以减少耐药菌株的产生。

Objective： To study the distribution and drug - resistance of the pathogens in tumor patients. Methods： Retrospective surveys of nosccomial infection in 512 cases from tumor hospital in Jilin were carried out from Jatmary 2005 to Jaunary 2006 , the pathology analysis and the drug sensitivity test were done for cases with tumor. Results：The main pathogens were Gram - negative bacteria （67.7% ） .Among them ,Escherichia was the highest {31. 25 % ） , then Klebsiella pneumonia （25.39% ）, then Klebsiella pneumonia （ 19.9 % ） .After it ,fungus had 18.16%. The number of Gram - positive organisms was 15.61% , the main pathogenswere staphylococcus attrous （7.4% ）. Conclusion： The antibiotics should be used reasonably , which can reduce the development of drug - resistant strains.
