Histopathology of cecal tissues of the normal bird (G1), SMC-treated birds (G2), E. tenella-challenged birds and examined on the 7th day post infection (G3), challenged and treated birds with SMC low dose (G4), high dose (G5), and diclazuril (G6). G1 and G2 (arrows indicate normal intestinal crypts), G3 (arrowheads indicate desquamation of the intestinal epithelium and arrows reveal severe infection of the intestinal crypts with parasitic schizonts), G4 (arrow indicates decrease the parasites within the intestinal mucosa), G5 (arrow indicates very few parasites), and G6 (arrow indicates moderate number of coccidial parasitic stages), H&E stain, bar = 200 μm.
