  1. Animals #1c-12c are from the Johne control herd. Animals #13c-17c are from a separate herd, the Control for a mastitis study. Note all six phage/qPCR positive animals are in the Johne control herd. Two animals were IFN-γ positive as were five with phage/qPCR. None of IFN-γ and phage/qPCR positives overlapped
