细菌性腹泻739例病原菌分布和耐药性分析

目的：了解细菌性腹泻患者的细菌菌群分布及耐药性特征,为预防治疗细菌性腹泻提供依据。方法：应用回顾性调查分析的方法,对我院2007～2010年739例细菌性腹泻患者粪便分离出的病原菌及细菌的耐药性进行分析。结果：分离鉴定出病原菌54株,总检出率为7.3%.病原菌以志贺菌36/54株（66.7%）居首位;鼠伤寒沙门氏菌9/54株（16.7%）;念珠菌9/54株（16.7%）。各菌属对抗生素的敏感率不同,第四代头孢菌素较敏感,敏感率在90%以上。药物耐药性的大小依次为：青霉素类、氨基糖甙类、磺胺类、青霉素类复方制剂、喹诺酮类及头孢菌素类;碳烯青霉类未检出耐药菌。结论：志贺菌属是细菌性腹泻的首要病原菌。同时细菌性腹泻病原菌的耐药性在逐渐增加,应对腹泻患者进行耐药性监测,合理应用抗生素。

Distribution and antibiotic resistance in 739 cases of infectious diarrhea pathogen

Objective:To analyze the microbes distribution and antibiotic resistance characteristic of the infectious diarrhea patients,and to supply guidance for prevention and cure.Methods: The character and resistance of the pathogenic bacteria,isolated from 739 cases of patients' stools during 2007 to 2010 in our hospital,were analyzed by retrospective study.Results:Fifty-four cases of pathogens were isolated and identified,the isolation rate was 7.3 %(54/739).Shigella bacteria(36/54) 66.7% % was the first pathogen...
