Histological changes in the cecum of rats infected with E. dispar. A Flat surface in cecum section of infected rat with E. dispar 7 days post-infection. Showed flat surface of mucosa (M), elongated crypts (C) lined with goblet cells (G), and infiltration of inflammatory cells (F). H&E stain ×379. B Transverse cecum section of infected rat with E. dispar 14 days post-infection. Showed the crypts (G) extend downward and penetrate the lymph nodule with active germinal center (N), heavy infiltration of inflammatory cells (F). H&E stain, ×379..C Transverse cecum section of infected rat with E. dispar 28 days post-infection. Showed unclear mucosal layer (M), deep crypts (de), mild degeneration of some crypt base (c), and regular muscular mucosa (MM) and submucosa (SM). H&E stain ×379
