泌尿系感染细菌的分布及药敏结果分析

Analysis on the distribution and drug sensitivity resuits of bacteria in urinary system

目的探讨本院泌尿系感染细菌的分布及耐药状况。方法统计近两年来尿培养的结果,对658株细菌及药敏结果进行回顾性分析。结果感染的细菌以革兰氏阴性杆菌为主,共522株,占79.3%。革兰氏阴性菌以大肠埃希菌最多,共375株,占57.0%。革兰氏阳性菌为136株,占20.7%,其中屎肠球菌68株,占10.3%,粪肠球菌41株,占6.2%。大肠埃希菌对亚胺培南耐药率最低,肠球菌对万古霉素和替考拉宁的耐药率最低。结论泌尿系感染的细菌以肠杆菌为主,对药物的耐药率明显升高,临床医生应根据药敏结果合理选择抗菌药物进行治疗,不应盲目经验用药,减少和控制细菌的耐药性。

Objective To investigate the distribution and drug resistance of bacteria in urinary system infection.Methods Statistics for the last two years of urine culture results,658 strains of pathogenic bacteria and drug sensitivity test results were retrospectively analyzed.Results The gram negative bacilli were predominant becteria,a total of 522 strains,accounted for 79.3%,in which escherichia coli was given priority to a total of 375 strains,accounted for 57.0%.Gram positive bacteria was 136 strains,accounted for 20.7%,in which enterococcus faecium was 68 strains,accounted for 10.3%,enterococcus faecalis was 41 strains,accounted for 6.2%.The drug resistance rate of escherichia coli to imipenem was the lowest,and enterococci to vancomycin and teicoplanin was the lowest.Conclusion The main bacteria are enterobacteriaceae in urinary system infection,which are highly resistant to antibacterial drugs.So clinical doctors should rationally select antibiotics in the treatment according to drug sensitivity results,avoiding bindly using antibiotics so as to reduce and control drug resistance.
