2011-2012年大连市感染性腹泻病原监测结果分析

Analysis on pathogenic surveillance results of infectious diarrhea in 2011 in Dalian

目的了解大连地区2011-2012年感染性腹泻病原菌的种类和流行特征,为感染性腹泻的预防控制和临床治疗提供依据。方法采用常规粪便培养方法,对分离菌做血清学分型,用MicroScan WalkAway-40全自动细菌生化鉴定仪对分离菌做生化鉴定。结果两年共监测109例腹泻患者样本,检出感染性腹泻病原菌22株,阳性率20.18%,其中副溶血弧菌所占比例最大,其次为志贺氏菌。结论副溶血弧菌是目前大连地区感染性腹泻的首要病原菌,志贺氏菌次之,应依据此监测结果做好今后大连地区腹泻病的防治工作。

Objective To understand the epidemic characteristics and types of infectious diarrhea pathogens from 2011 to 2012 in Dalian,so as to provide references for the prevention and control as well as clinical treatment of infectious diarrhea.Methods The pathogen strains were isolated by routine stool culture and made serological typing.The biochemical identification of the isolates were carried out by automated microbiology analyzer MicroScan WalkAway-40.Results 22 intestinal pathogenic bacteria were detected out from 109 samples,and the positive rate was 20.18%,in which parahaemolyticus accounted for the largest proportion,followed by shigella.Conclusions Vibrio parahaemolyticus is the primary pathogen caused infectious diarrhea in Dalian presently,followed by Shigella.Based on the surveillance results,prevention and control work of diarrheal disease in Dalian should be carried out in future.
