Agarose gel electrophoresis of amplified products for eae (490 bp), stx2 (349 bp), and stx1 (110 bp) of E. coli O157:H7 isolates, respectively. Key: lane M: DNA ladder, lane 1: known positive control (taken from previous works), lanes 2–6: samples (those which have a band are positive to the gene), and lane 7: negative control.
