a) All strains were isolated from human faeces. In bold: serotypes previously associated with Stx-production . H-type in [brackets] indicates presence of non-motile strains that were investigated for their fliC genotype .
b) two O114:H2 strains were positive for the EHEC virulence plasmid associated etpD gene.
c) EPEC O119:H2 were previously reported as atypical EPEC reacting with bfpA probe . One each of the O119:H2 strains was positive for EHEC virulence plasmid associated genes espP and etpD
