Flow cytometric analysis of T lymphocytes. Flow cytometric analysis of the percentage of CD4+ intraepithelial lymphocytes (IEL) in caecum of broiler-type (BT) (a, c) and layer-type (LT) birds (b, d) fed with either broiler feed (bf) or layer feed (lf). Birds had been C. jejuni-inoculated at 1 (Exp. 1) (a, b) and 22 (Exp. 2) (c, d) days post hatch. CD4+ T cells were gated within the CD3+ IEL population. Asterisk letters indicate significant differences between C. jejuni-inoculated (C. jejuni) and C. jejuni-free control (con) groups at the indicated days post C. jejuni inoculation (n = 6/group, p < 0.05)
