Histopathological changes in the caeca of chickens from the different groups in Experiment 2 post-challenge with E. tenella. On Day 7 pi, the caeca of chickens from each group in Experiment 2 (n = 7) were fixed in neutral buffered formalin (10%), embedded in paraffin, sectioned and stained with haematoxylin and eosin (HE). A No histopathological changes were observed in the caecal tissues of the chickens in the PBS group. B Histopathological lesions in caecal tissues of the chickens in the infection control group displayed detachment of the intestinal villi, necrosis of the epithelial cells and congestion of the veins. In the C L/EA + L/LB(+)and D M/EA + M/LB(+)groups, the structures of caecal tissues were relatively complete, and a small number of red blood cells were observed. E In the H/EA + H/LB(+)group, no obvious histopathological changes to the caecal tissues were observed, and the intestinal villi were arranged regularly.
