Fig. 8From: Protective effects of a food-grade recombinant Lactobacillus plantarum with surface displayed AMA1 and EtMIC2 proteins of Eimeria tenella in broiler chickensDetection 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 intactBack to article page
