Fig. 2 in Parasitic development in intestines and oocyst shedding patterns for infection by Eimeria uekii and Eimeria raichoi in Japanese rock ptarmigans, Lagopus muta japonica, protected by cages in the Southern Japanese Alps

Fig. 2. Histopathological photomicrograph of a section of the intestines of dead chicks during cage protection in 2018. Figs. A and B show developmental trophozoites (arrows) and schizonts (arrows) of Eimeria spp. at the epithelial cells of the colon (Chick c) and ileum (Chick a), respectively. Some zoites (arrows) invade into submucosa (ileum of Chick b) (Fig. C). Figs. D, E, and F show the sexual zoites or cavities after releasing oocysts (arrows) of the ileum (Chick a), ceca (Chick d), and ileum (Chick c). Arrowheads in Fig. F indicate hemorrhages in the intestinal mucosa.
