a) in bold: serotypes previously associated with Stx-production [3]

b) Origin and numbers (in brackets) of strains h = human, a = animal, f = food

c) Four O26:H11 strains from humans and seven from animals were positive for the EHEC-plasmid associated ehxA gene.

d) All strains were positive for ehxA.

e) One strain was positive for ehxA.

f) serotypes and strains represented each by one isolate only: O2:H8 (a), O3:H5 (f), O3:H40 (h), O15:H11 (a), O21:H25 (h), O22:[H7] (h), O45:H7 (a), O71:H40 (h), O76:H41 (a),O84:[H2] (a), O109:H25d (a), O117:H25d (h), O121:H- (h), O121:H19d (h), O127:H8 (h), O128:H8 (h), O153:H14 (a), and Orough:[H7] (h)
