γδ T cell subsets in Map infection sites of naïve and vaccinated calves. The percentage of γδ T cells was significantly higher in late lesions compared to early lesions in naïve calves (panel a, *P = 0.0043) but not vaccinates. In panels b and c, WC1- γδΤ cells were recruited more heavily to infection sites of naïve calves compared to vaccinates (*P < 0.05) and the number of WC1 + γδ T cells significantly increased over time in infection sites of naïve calves but not in vaccinates (**P < 0.05).
