摘要
目的 了解徐州市不同地区大肠埃希菌O157∶H7出血性肠炎流行季节动物的发病及带菌率。方法 在不同流行强度的地区设调查点 ,调查猪、鸡、牛、羊的发病情况 ;并采集其粪便 ,用免疫磁珠法进行病原分离培养。结果 6个调查点共调查动物 5 65头 ,发病 3 5头 ,罹患率 6 19% ;共采集猪、鸡、牛、羊等动物粪便标本 90 1份 ,分离出大肠埃希菌O157∶H713 0株 ,总带菌率 14 4% ,其中以牛、羊带菌率较高 ,分别为 2 1 9%、 19 4%。结论 在大肠埃希菌O157∶H7出血性肠炎流行季节各种动物都有不同比例发病 ,不同地区的动物带菌率也不尽相同。提示加强动物大肠埃希菌O157∶H7发病率及带菌率的调查对疫情分析与疾病控制有重要意义。
Objective To understand Incidence and Carrier Rate of Escherichia coli O 157 ∶H 7 among animals. Methods Surveillance spots were set up in different areas,to survey the Cases and Collect feces of pigs,chickens,sheep,cattle to culture for O 157 ∶H 7 with immunomagnetic separation. Results Thirty and five Cases were find out,with a overall attack rate 6.19%,One hundred and Thirty strains of O 157 ∶H 7 were separated from 901 feces of different animals in six spots,with a overall positive rate 14.4%.The positive rate of cattle and sheep were 21.9% and 19.4%,respectively. Conclusion The affack rate and the positive rate of O 157 ∶H 7 were correlated to the indidence of the area.The affack rate and the positive rate were difference in the different areas.Data indicated that it was important to enforce the surveillance of O 157 ∶H 7 in animals to better predict and control of the disease.
