Immunohistochemical detection of Bu1+ B (a, b) and CD4+ (c, d) as well as CD8 + (e, f) T cells in the lamina propria of the caecum of mono- and co-inoculated birds of Exp. A (a, c, e) and Exp. B (b, d, f) (n = 6/group). pbi post bacterial inoculation; pvi post IBDV (virus) inoculation. Error bars indicate the standard deviation (SD). abcletters indicate significant differences between groups within the same experiment at the indicated time points (P < 0.05). control = non-inoculated control, C. jejuni = C. jejuni mono-inoculated group, vvIBDV = vvIBDV mono-inoculated group, co-inoculation = vvIBDV + C. jejuni co-inoculated group
