There are many species of [[Eimeria spp.|''Eimeria'']] and [[Isospora spp.|''Isospora '']]found in pigs, but ''Isospora suis ''is the only [[:Category:Coccidia|coccidia]] of clinical pathogenic importance. It is primarily a disease of the young (1-3 week old) piglet and can be a cause of economic loss in pig herds. Research has shown that clinical coccidiosis is present in herds in all parts of the UK and worldwide.
