Medical Definition of Coccidium
1. Common name given to protozoan parasites (order Eucoccidiida) in which schizogony occurs within epithelial cells, generally in the intestine, but in some species in the bile ducts and kidney; the final product of sexual fusion and differentiation that occurs within the host, the oocyst, generally passes to the soil in the faeces, undergoes sporulation, and then acts as the infective form for another host. Coccidia are parasitic in most domestic and wild birds and mammals, occasionally in man, and are highly host-specific; the majority are nonpathogenic, but certain species rank among the most serious and economically important pathogens, causing coccidiosis in birds and mammals. See: Eimeria, Isospora. Origin: Mod. L. Dim. Of G. Kokkos, berry (05 Mar 2000)
