(A). Prevalence of animals positive to the caudal fold test (CFT) in each group at the different sampling times. (B). Percentage of positive animals to the interferon-gamma release assay (IGRA). Kruskal–Wallis test and Dunn’s post test. * Prevalence that differed significantly between the studied groups, p < 0.05. The dotted vertical line and gray arrow indicate the day of the re-vaccination. (C,D). Incidence of positivity for both CFT and IGRA, respectively, represented by the Kaplan–Meier analysis. TST: Tuberculin skin test. Dpv: days post vaccination. Dprv: days post re-vaccination. IFNg: Interferon gamma.
