Detection of specific IgY in sera (a) and SIgA in intestinal washes (b) from chicks after boosting immunization. The data shown represent mean ± S.E.M (n = 5), which were compared by a one-way ANOVA (*P < 0.05, **P < 0.01, and ***P < 0.001). The samples were measured with 3 repeats. c Pathological cecum damage 7 dpi. Sample sections were stained using HE (×100 magnification); PBS: PBS control group. The villi and glands of the cecum are clearly visible and appear intact. PBS-challenge: The PBS-challenge group exhibits seriously damaged cecum villi and blurred gland was with blood cells and inflammatory cells present in the submucosa. A large number of coccidial oocysts can be found in the cecum lumen. Lp/pLQa-pgsA′: Lp/pLQa-pgsA′ immunized, followed by a challenge with E. tenella. The cecum villi were severely damaged and the glands appear blurred. Lp-12: Lp-12 immunized, followed by a challenge with E. tenella. The cecum villi were partly exfoliated, but the villus structure and the submucosal tissue remained relatively intact
