Chicken is the only natural host of coccidiosis. Emeria spp have complex life cycle which are continuous process that developed into host chicken. Site of infection defined where Emeria spp multiply in the intestinal tract of poultry. There are eight species but they are also host specific. One Emeria species can not grow in others host like emeria tenella only causing bloody diarrhea in chicken but never others species like Turkey, duck, pigeon etc.

Emeria not only host specific but also tissue specific. For example E. acervulina only developed in the epithilium of duodenum but not others organ. So Every Emeria spp have one site of infection in the intestinal tract of chicken.
