*HUSEC, hemolytic uremic syndrome–associated enterohemorrhagic Escherichia coli; EHEC, enterohemorrhagic E. coli. For each serotype, the multilocus sequence type (ST) and the corresponding clonal complex (CC) are given in accordance to the E. coli multilocus sequence typing website (http://web.mpiib-berlin.mpg.de/mlst/dbs/Ecoli). Furthermore, the presence (+, present; – absent) of the intimin gene (eae), the Shiga toxin gene (stx), and its subtype(s) are specified. nt, not typeable by the O and H antisera used; H, nonmotile; OR, O rough (autoagglutinable strain); NA, not assigned.
†2dact, stx2d-activatable.
