部分ESIEC菌株存在耶尔森氏菌HPI毒力岛

A “High-pathogenicity Island” of Yersinia Enterocolitia Exsited in Entero-SLT-Producing and Invasive E.Coli Strains

    摘要
  • 摘要: 本文应用小肠结肠炎耶尔森氏菌毒力岛HPI上的irp2、fyuA基因和大肠杆菌染色体上asnT -tRNA位点检测的引物 ,对 43株肠产志贺样毒素且具侵袭力的大肠杆菌 (ESIEC)进行了PCR检测。发现约 34 9%的菌株irp2、fyuA引物扩增阳性 ,而这部分菌株asnT -tRNA位点引物扩增为阴性 ,证实ESIEC中确有耶尔森氏菌毒力岛的irp2、fyuA基因 ,并且也在染色体上asnT -tRNA位点插入。

     

    Abstract: The irp-2 and FyuA genes of “high-pathogenically island” (HPI) of Yersinia enterocolitia and asnT-tRNA locus for HPI insertion on the chromosome DNA were detected for 43 strains of entero-SLT-producing and invasive Escherichia Coli(ELIEC) by PCR method. We demonstrated that the irp2 and fyuA genes of Y.enterocolitia were existed in 34.9% of ESIEC strains tested, and mutated asnT-tRNA locus was observed in ESIEC strains carrying irp2 and fyuA genes. This findings suggested that some ESIEC strains carried HPI island needed to be clarified.
