Eimeria christenseni and Eimeria arloingi were used separately to infect one month-old goat kids which were then killed 34 days post-infection. Their small intestines contained small nodular lesions made of several endogenous stages mainly macrogametocytes and macrogametes. Electron microscope studies of macrogametocytes revealed a prominent central nucleus and nucleolus. Other cellular components were mitochondria, wall forming bodies(WFB) type 1( homogenous) and type 2(reticular). Polysaccharide granules of E.christenseni had a chain like arrangement in the young cells, and increased dramatically with maturation of the macrogemetes to become the main cytoplasmic component along with the WFB. Type 1 WFB were peripheral while type 2 were more central but in E.christeseni macrogametes, some type 2 WFB appeared to give rise to membranous vesicles at the areas of wall formation.. The macrogamete nucleus was small and usually indented with polysaccharide granules and reticular bodies, named nuclear derived bodies(NBD), arising from the perinuclear regions. Within the periparasitic areas of both species, membranous/dark bodies were seen. E. arloingi had a large and well defined parasitophorous vacuole(PV), within which an inner lighter, and outer layer with dark granules were found. Both species had some poorly developed intravacuolar tubes(IVT), which occurred at certain points in the case of E.arloingi, while in E.christenseni, they had a diffuse distribution
