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 types and epidemiological characteristics of infectious diarrhea pathogens in Dalian from 2011 to 2012 and provide evidence for the prevention and control of infectious diarrhea and clinical treatment. Methods The routine stool culture method was used to classify the isolates. The biochemical identification of the isolates was performed with a MicroScan WalkAway-40 automatic biochemical analyzer. Results A total of 109 cases of diarrhea were detected in two years. Twenty-two strains of infectious diarrhea were detected, the positive rate was 20.18%. Vibrio parahaemolyticus accounted for the largest proportion, followed by Shigella. Conclusion Vibrio parahaemolyticus is the most important pathogen of infectious diarrhea in Dalian. Shigella is the second most important cause of diarrhea in Dalian.
