PATHOLOGY

Detailed explanation-1: -Coccidia are intestinal parasites of mammals, birds, reptiles, and certain amphibians. They live chiefly in the intestinal wall of their host. The disease caused by coccidian parasite is referred to as coccidiosis. Coccidia in dogs occur when ingested from contaminated environment.

Detailed explanation-2: -Otherwise, coccidia are host-species specific and there is no cross-immunity between different coccidial species in the same host. Intercurrent infections are common and may be exacerbated because coccidiosis can be immunosuppressive. The life cycle is complex but is all completed within the one host producing oocysts.

Detailed explanation-3: -Coccidiosis is an intestinal tract infection caused by a single-celled organism (protozoa) called coccidia. Coccidiosis typically refers to gastrointestinal infections with the Isospora species (sometimes called Cystoisospora) of coccidia, though other species can be found.

Detailed explanation-4: -Coccidiosis which is caused by the apicomplexan parasite of the genus Eimeria has seven known species which affect the different parts of the intestinal tract of chickens. The disease which occurs by ingestion of sporulated oocyst has been associated with poor poultry management system.
