Coccidiosis is a disease of poultry which is of worldwide importance, both economically and for animal welfare reasons. It is a disease of over-crowding and poor hygiene, hence it is prevalent in intensive chicken farming globally, however, it can affect birds in any facilities. Although outbreaks of the disease are not common, coccidia remains in most flocks as a subclinical disease, which in times of stress can establish into a clinical disease. Many commercial units now use prophylactic drugs in order to try to control the disease.

There are 7 important coccidia species in chickens, all which falle [[Eimeria spp.|''Eimeria'']] genus. <br>There are 4 '''malabsorptive''' species, which range from low to moderate pathogenicity and 3 '''haemorrhagic''' species, which are all highly pathogenic. All seven species have different predilection sites in the alimentary system and cause unique pathological changes.
