Isospora belli and Isospora suis complete the entire life cycle in a single host, while Isospora felis and Isospora ohioenesis are facultative or heteroxenous and need intermediate hosts to complete their life cycle (Lindsay and Blagburn, 1994; Lindsay et al., 1997; Tenter et al., 2002; Morrison et al., 2004).
