*CC, clonal complex; ST, sequence type; EHEC, enterohemorrhagic Escherichia coli; HUS, hemolytic uremic syndrome; NA, not assigned.
†% of strains of a CC and ST among all 169 non-O157 EHEC isolated from HUS patients.
‡H–, nonmotile; OR, O rough (autoagglutinable strain); nt, not typeable by the E. coli O and H antisera used.
§Number of strains of the serotype that belonged to the respective ST; if no number is given, all strains of the serotype belonged to the respective ST.
¶ST659 is a single-locus variant of ST342.
