Animals were vaccinated at week 0 and challenged at week 8.
a One goat of the Control group was euthanized at week 16.
b PPD-B, M. bovis purified protein derivative; two criteria were used for positivity: C, Conservative (S/P ≥ 35%), and S, Stringent (S/P ≥ 16%).
c EC, ESAT-6/CFP-10 protein mixture; the criterion for positivity was S/P ≥ 16%.
