None of the STEC strains isolated in Galicia from human patients between 1992 and 2011 belonged to serotype O104:H4, the serotype implicated in the German outbreak. Table 6 shows the most frequent STEC serotypes found
Fig. 2. Dendrogram of the XbaI macrorestriction profiles of 21 STEC strains of serotype O157:H7 isolated in Galicia, northwestern Spain. Strain code, stx1, stx2, year of isolation and origin, are shown on the right side of the dendrogram.*O157-809 strain isolated from a patient with HC, O157-816 strain isolated from a sample of frozen beef consumed by the patient, and O157-810 strain isolated from an asymptomatic relative . **O157-718, O157-720 and O157722 strains isolated from two patients and an asymptomatic carrier of the same family, respectively. Unpublished data.
