Individual red deer antibody levels (in ELISA percentage, E%) to bovine purified protein derivative (bPPD) measured by using ELISA immediately before and until 60 days post-inoculation of M. bovis. Serum samples with E% values greater than 100 were considered positive (horizontal grey line). *Significant differences (p < 0.05) between pre-inoculation values and those from different post-inoculation time points
