PCR identification of C. jejuni and cpa-positive C.perfringens. For C. jejuni identification A: Lanes 1 and 19, C. jejuni genomic DNA; lanes 2 and 18, 100bp DNA ladder; lanes 3 and 17, no template control; lanes 4, 5, 6, 7, 10, 11, 15 and 16, C. jejuni hipO positive samples; lanes 8, 9, 12, 13 and 14, C. jejuni hipO gene negative samples. For C. perfringens identification. Samples in lanes 1-10 and 11-19 were run on the top and bottom halves of the same gel, respectively. B: Lanes 1 and 20, C. perfringens genomic DNA; lanes 2 and 19, 100bp DNA ladder; lanes 3 and 18, no template control; lanes 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 and 14, 15, 16 and 17, C. perfringens cpa gene positive samples. Lane 15 has a faint band. All samples were tested at least twice. Samples in lanes 1-10 and 11-20 were run on the top and bottom halves of the same gel, respectively
