A summary of standard test results compared with the data from the phage/qPCR experiments. In the Control animals the ELISA and fecal PCR have no positives, whereas IFN-γ was 12% and phage / qPCR 35% positive. ELISA (31%+) is least sensitive in the Johne animals. IFN-γ (69%+), fecal PCR (75%+) and phage / qPCR (72%+) the most sensitive
