Abstract:

Effacement of the microvilli and intimate attachment to the enterocytes (AE lesions) are two common properties of enteropathogenic (EPEC) and many verotoxigenic (VTEC) E. coli isolates from humans and animals. However not all of the several chromosomal and plasmidic genes and loci involved in the pathogenesis of the human EPEC strain E2348/69 are present in EPEC and VTEC isolates from animal species. We here report that in addition to verotoxin-encoding genes, bovine VTEC isolates harbour a variant of the original eaeA gene, confirming previous results, but neither the eaf nor the hfp loci …
