Results of PCR with the use of 10 μL of MagaCell-IgY beads to immunocapture MAP strain ATCC 19698 spiked in bovine feces at concentrations of 2 × 10³ cells/g (lanes 1 to 3), 2 × 10⁴ cells/g (lanes 4 to 6), and 2 × 10⁵ cells/g (lanes 7 to 9). End-point titration was performed with extracted DNA run undiluted (N) and at dilutions of 1:10 (−1) and 1:100 (−2). Lane +C — positive-control DNA (ATCC 19698); lane +IC — positive internal-control DNA; lane −C — negative water control; lane M — 1-kb molecular weight marker.
