a
Ont, O nontypeable; OR, O rough; ND, serotype not determined.
b
STEC strains were isolated either from foods or from the feces of patients with uncomplicated diarrhea (D), bloody diarrhea (BD), microangiopathic hemolytic anemia (MHA), thrombocytopenia (T), or hemolytic uremic syndrome (HUS).
c
Determined by Southern hybridization analysis with a digoxigenin-labeled PCR product corresponding to the complete pilS open reading frame as probe and by PCR.
d
Determined by Southern hybridization analysis (22).
