PFGE patterns of XbaI-digested genomic DNAs of SF STEC O157:H− strains and control E. coli O157 strains. Lane S, molecular size standard (DNA from E. coli strain G5244 restricted with XbaI). In lanes 1 to 7, the following SF STEC O157:H− strains are shown: lane 1, 258/98; lane 2, 269/98; lane 3, 550/98; lane 4, 221/95; lane 5, 703/88; lane 6, 1995/96; and lane 7, 3573/98. In lanes 8 to 10, control E. coli O157 strains are shown as follows: lane 8, EDL933 (NSF STEC O157:H7); lane 9, 1083-36/91 (SF, Stx-negative E. coli O157:H45); and lane 10, 693/91 (SF, Stx-negative E. coli O157:H19).
