Agarose gel electrophoresis of fliC PCR products of SF STEC O157:H− strains and of control E. coli O157 strains after restriction with RsaI. Lanes M, molecular size marker (1-kb DNA ladder; Gibco BRL). In lanes 1 to 7, the following SF STEC O157:H− strains are shown: lane 1, 550/98; lane 2, 258/98; lane 3, 269/98; lane 4, 703/88; lane 5, 221/95; lane 6, 1995/96; and lane 7, 3573/98. Lanes 8 to 10 contain control E. coli O157 strains as follows: lane 8, EDL 933 (O157:H7); lane 9, 1083-36/91 (O157:H45); and lane 10, 693/91 (O157:H19).
