Abstract

The nomenclature of Sarcocystis and related protozoan genera is reviewed, and modern diagnoses of the genera Isospora, Toxoplasma, Besnoitia, Sarcocystis, and Frenkelia in the coccidian family Eimeriidae are given. S cruzi (Hasselmann 1926) comb. n., S. hirsuta Moulé 1888, and S. hominis (Railliet and Lucet 1891) comb. n. are recognized in the muscles of the ox Bos taurus; S. ovicanis Heydorn, Gestrich, Melhorn, and Rommel 1975, and S. tenella Railliet 1886 are recognized in the muscles of the sheep Ovis aries; S. bigemina (Stiles 1891) comb. n., S. cruzi, S. ovicanis, S. bertrami Doflein 1901, S. miescheriana (Kühn 1865) Lankester 1882, I. ohioensis Dubey 1975, I. canis Nemeséri 1959, Isospora sp. n. Dubey, and Isospora sp. n. Trayser and Todd are recognized in dog (Canis familiaris) feces; and S. hirsuta, S. tenella, S. muris (Blanchard 1885) Labbé 1899, B. besnoiti (Marotel 1912) Henry 1913, Besnoitia sp. n. Frenkel, T. gondii (Nicolle and Manceaus 1908) Nicolle and Manceaux 1909, T. hammondi (Frenkel 1974) Levine and Nye 1976, I. rivolta (Grassi 1879) Wenyon 1923, and I. felis Wenyon 1923 are recognized in cat (Felis catus) feces. Hoareosporidium Pande, Bhatia, and Chauhan 1972 is considered a synonym of Sarcocystis.
