COCCIDIA 583 



E. necatrix Johnson. In the small intestine (schizonts) and caeca 

 (oocysts) of chicken; a cause of chronic coccidiosis; oocysts obovate, 

 13-23 n by 11-18/*; sporulation in 48 hours (Tyzzer, 1932). 



E. praecox J. In the upper third of the small intestine of chicken; 

 oocysts ovoid, 20-25/* by 15.5-20/*; sporulation in 48 hours. 



E. meleagridis Tyzzer. In the caeca of turkey; apparently non- 

 pathogenic; oocysts, ellipsoidal, 19-30/x by 14. 5-23 /* (Tyzzer, 1927, 

 1932). Coccidiosis in turkey (Hawkins, 1952). 



E. meleagrimitis T. In the lower small intestine of turkey; some- 

 what similar to E. mitis; oocysts, 16.5-20.5/* by 13.2-17.2/* (Tyzzer, 

 1929). 



E. adenocides Moore and Brown. In the ileum, caeca and rectum 

 of turkeys; oocysts about 25.6/* by 16.5/*; highly pathogenic to young 

 turkeys (Moore and Brown, 1950). 



E. truncata (Railliet and Lucet). In the kidney of geese; oocysts 

 truncate at one pole, ovoid, 14-23/* by 13-18/*; some observers find 

 this coccidian fatal to young geese. 



E. anseris Kotlan. In the intestine of geese; oocysts spherical or 

 pyriform, 11-16/* in diameter. Coccidia in Canada goose (Levine, 

 1952a). 



E. labbeana Pinto. In the gut of domestic pigeon; oocysts some- 

 times light brown, 15-26/* by 14-24/*. 



E. dispersa Tyzzer. In the small intestine of bob-white quail and 

 pheasant; oocysts ovate, 18.8-22.8/* (quail), smaller in pheasant, 

 without polar inclusion; sporulation in about 24 hours. 



E. amydae Roudabush. In the intestine of Amyda spinifera; 

 oocysts oval with a thin wall, 17-24/* by 12-17/*; elliptical spores 

 about 11-16/x long (Roudabush, 1937). 



E. chrysemydis Deeds and Jahn. In the intestine of Chrysemys 

 marginata; oval oocysts 21-27/* by 13-18/*; fusiform spores 12-14/* 

 by 5-8/* (Deeds and Jahn, 1939). Other reptilian species (Rouda- 

 bush, 1937) 



E. ranarum (Labbe) (Fig. 248, o). In the gut epithelium (nuclei) of 

 frogs; oocysts about 17/* by 12/*. 



E. prevoti (Laveran and Mesnil) (Fig. 248, p). In the gut epithelium 

 of frogs; oocysts about 17/* by 12/*. 



E. ranae Dobell (Fig. 248, q). In the gut of frogs; oocysts 22/* by 

 18/x. 



Species of Eimeria are often parasitic in fishes used for human 

 consumption, and thus may appear in faecal matter. A few examples 

 will be mentioned here. 



E. sardinae (Thelohan) (E. oxyspora Dobell) (Fig. 248, r). In the
