尿路感染病原菌分布及耐药性分析

目的探讨尿路感染病原菌分布及对抗菌药物的耐药情况,为临床合理用药提供依据。方法回顾性分析2007-2009年医院尿液培养阳性的239株病原菌的种类和耐药性。结果 239株病原菌以革兰阴性菌为主,占66.1%,最常见的是大肠埃希菌,占51.1%,其次为肺炎克雷伯菌,占7.9%;革兰阳性菌以肠球菌属为主,占13.8%;真菌为10.5%;革兰阴性杆菌对氨苄西林、庆大霉素、磺胺甲噁唑/甲氧苄啶的耐药性>60.0%,对亚胺培南100.0%敏感;革兰阳性球菌对头孢唑林、阿莫西林/克拉维酸、红霉素、青霉素、阿奇霉素等的耐药性>70.0%。结论大肠埃希菌是尿路感染病最常见的病原菌,尿路感染病原菌对常用的抗菌药物耐药性较高,常为多药耐药;加强病原菌检测及耐药性监测,对指导临床合理用药,减少多药耐药菌产生,降低尿路感染率具有重要意义。

Distribution and drug resistance of pathogens causing urinary tract infection

OBJECTIVE To approach the distribution characteristic and drug resistance status in pathogens from infected urinary tract,to provide the basis for clinical medication.METHODS Review analysis was performed for types and drug resistance of 239 strains of pathogenic bacteria in hospital urine culture positive.RESULTS Gram-negative bacteria(66.1%) were mainly in 239 example pathogens,the most common was Escherichia coli(51.1%),followed by Klebsiella pneumoniae(7.9%);Enterococcus were the majority(13.8%) in Gram...
