a–d Comparison of parasite establishment within ileum and caecum epithelia of experimental and control animals. a–d Demonstrates parasite establishment in a vacuole within the epithelia of ileum and caecum in only experimental animals and not the controls. Both a and b show the establishment of the parasite in the epithelial mucosa of the ileum and caecum in experimental animals, while c and d (controls) show normal ileum and caecum mucosa without parasite infection. a Photomicrograph of ileum section with oocysts embedded in mucosa lining (×1000). b Photomicrograph of caecum section with oocysts embedded in mucosa lining (×400). c Photomicrograph showing no oocysts in mucosa of normal ileum epithelia in controls (×400). d Photomicrograph showing no oocysts in mucosa of normal caecum epithelia in controls (×400)
