- •
The screening of Escherichia coli isolates from cattle showed that 11.9% of E. coli isolates harbored EHEC-hlyA.
- •
The EHEC-hlyA harboring isolates were related to EHEC (72%), ETEC (11.1%), and EPEC (7.4%) pathotypes.
- •
The stx-/eae+ strains carried O island 57 (OI-57) molecular marker(s) that may reflect the EHEC genomic backbone.
- •
Two strains had hybrid genotypes: EHEC/ETEC and EPEC/ETEC, both belonging to phylogenetic group A.
