Figure 4: (a) A small-intestinal section of a rat examined 2 weeks postinfection (group V) showed destruction of the surface epithelial lining (black arrows) with subepithelial dense inflammatory infiltrate, mainly eosinophils (E), with lymphocytes (L) and abundant goblet cells (G), and there was inflammatory edema (ed) (H&E, × 200). (b) A small-intestinal section of a rat examined 2 weeks postinfection (group V) showed loss of the intestinal surface epithelial lining (black arrows) and subepithelial dense inflammatory infiltrate, mainly lymphocytes (L) and a divided oocyst (yellow arrow) (H&E, ×200). (c) A small-intestinal section of a rat examined 2 weeks postinfection (group V) showed a dividing oocyst (10×7 mm) with the oocyst wall (OW) and two sporocysts (SPC) (H&E, × 1000). (d) A TEM photo of a ratfs intestinal tissue (2 weeks postinfection) showed abnormal epithelial cells with the nucleus (N), abnormal mitochondria (M), and rarified cytoplasm (C) in group V. (e) A TEM photo of a ratfs intestinal tissue (2 weeks postinfection) showing a dividing oocyst with the oocyst wall (OW), sporocyst (SPC), and sporozoites (SPR) in group V.
