A subclass of protozoans commonly parasitic in the epithelial cells of the intestinal
tract but also found in the liver and other organs. Its organisms are found in both
vertebrates and higher invertebrates and comprise two orders: EIMERIIDA and EUCOCCIDIIDA
Note générale sur le champ d'application :
infection = COCCIDIOSIS; "coccidial" refers to COCCIDIA: do not confuse with "coccidioidal"
(refers to COCCIDIOIDES, a fungus); coordinate with specific protozoal terms (ANTIGENS,
PROTOZOAN, etc) if pertinent
