Multiplex PCR for S. aureus enterotoxin genes. Lane (L): 100 bp ladder DNA marker, Lane (Pos): control positive containing DNA of 4 S. aureus strains harboured Seb (164 bp), Sea (102 bp), See (209 bp), Sed (278 bp) and Sec (451 bp) genes. Lane (Neg): control negative. Lanes (1, 2, 3, 4, 5, 6, 7, 8, 9 and 10): isolates positive for Sed gene (278bp). Lanes (1, 2, 3, 5, 7, 9 and 10): isolates positive for Sea gene (102bp). Lanes (1,2, 3, 6and 8): isolates positive for See gene (209bp).
