摘要
目的:了解郑州市肠出血性大肠杆菌O157∶H7在腹泻病人中的检出情况和宿主动物带菌及毒力基因情况。方法:对采集的宿主动物和腹泻病人粪便及食品应用免疫磁珠富集分离法进行大肠杆菌O157∶H7分离和鉴定。结果:郑州市内共发现3例肠出血性大肠杆菌O157∶H7感染病例,首次从腹泻病人中检出产毒O157∶H7菌株,采集5种以上动物粪便标本共计475份,从牛粪(247份)中分离到16株O157∶H7,检出率为6.48%,从羊粪(33份)中分离到3株O157∶H7,检出率为9.10%,并检出3株产毒O157∶H7菌株。采集5类市售食品共146份,未分离到O157∶H7。结论:郑州市存在发生肠出血性大肠杆菌O157∶H7感染暴发或流行的潜在危险。
Objective： To understand the Escherichia coll O157：H7 cartier rate of host animals and the toxic gene of the strains in Zhengzhou city. Methods： Stool samples of host animals, patients of diarrhea, and foods were collected and detected for E. coli O157：H7 by using immunomagnetic sand method. Results： 3 cases of E. coli O157：H7 infection in Zhengzhou city were discovered. Producing O157：H7 strains was first isolated from patients of diarrhea. 475 samples of the faeces which contain more than 5 species animals were collected, and 16 strains of E. coll O157 ： H7 were isolated from faeces of cattle, the detection rate was 6.48 %. And 3 strains of E. coli O157 ： H7 were isolated from faeces of lamb, the detection rate was 9.10 %. 3 strains of producing E. coli O157：H7 strains were isolated from host animals. Several kinds of food products were also collected, no strains of E. coli, O157：H7 were isolated. Conclusions： There was a potential risk of outbreak of E. coli O157：H7 infection.
