Objective: To describe the distribution of high-pathogenicity island (HPI) of Yersinia enterocolitica in enterotoxingenic E.coli (ETEC) and enteropathogenic E.coli (EPEC), and to understand the structure and function of HPI. Methods: PCR was used to detect irp2, fyua and asn-intB genes with subsequent sequence analysis of these genes.

2024年11月30日 · 【目的】本研究探讨了云南撒坝猪EPEC HPI毒力岛的摄铁功能与致病性之间的关系。 【方法】本试验通过摄铁实验对5株肠致病性E.coli (A-E)和CVCC1565铁载体的合成和在不同2，2’-联吡啶含量下的最低生长抑制浓度及对数期生长速率进行了测定，同时利用已构建的E.coli irp2基因缺失株和亲本株进行对比，检测HMWP2蛋白的表达，并通过半数致死量实验比较两者之间 …

该次研究首次在国内对大肠杆菌中强毒力岛的核心区的所有片段进行了检测,并发现耶尔森茵强毒力岛相对稳定的结构存在于ETEC、EPEC和EAggEC中:这些毒力岛大部分都整合到asn-tRNA位点,说明大肠杆菌中的毒力岛是水平转移而来.另外首次发现毒力岛在不同浓度的铁螫 ...

OBJECTIVE To describe the distribution of high-pathogenicity island (HPI) of Yersinia enterocolitica in enterotoxingenic E.coli (ETEC) and enteropathogenic E.coli (EPEC), and to understand the structure and function of HPI. METHODS PCR was used to detect irp2, fyua and asn-intB genes with subsequent sequence analysis of these genes.

Results: The irp2 and fyua genes of Yen HPI were investigated in E. coli strains. Among them, 30 strains were isolated from 93 Enterotoxigenic E. coli (ETEC) strains and 3 strains were positive in 10 strains Enteropathogenic (EPEC). HPI was also detected in Enteroaggregative E. coli (EAggEC) strain.
