ABSTRACT
Detection and distribution of eae gene in forty-four attaching and effacing Escherichia coli (AEEC) strains of animal origin were investigated. Association of distinct intimin alleles with phylogenetic background were assessed among strains in comparison with different serogroups. Phylogenetic analysis showed that 31 EHEC/eae+ STEC strains belong to groups A, B1 and E, 13 EPEC strains segregated in B1 and B2. Moreover, group A possessed the eae gamma2/theta type, group B1 the eae beta1, eae kappa, eae zeta, and eae epsilon types, group B2 the eae alpha1, eae alpha2 and eae iota types, while the group E possessed the eae gamma1 type. The presence of numerous eae-types show that EPEC and EHEC/eae+ STEC tested have a high genetic homology within each phylogenetic group.
