Interpretive Summary: Coccidia are a group of single celled parasites. This group of protozoa include important genera: Eimeria, Cystoisospora, Cyclospora, Sarcocystis, Toxoplasma,Neospora, Isospora that can cause serious illness in livestock, poultry, and humans and some species are zoonotic (parasites transmitted from animals to humans). The present paper summarizes biology of Neospora caninum, Toxoplasma gondii and Sarcocystis spp.. The definitive hosts excrete unsporulated (N. caninum, T. gondii) or sporulated (Sarcocystis spp.) oocysts in their feces after ingesting tissue cysts from the tissues of ruminant intermediate hosts. These coccidians can cause abortion and neonatal mortality in ruminants. This paper reviews information on etiology, life cycle, diagnosis, control and prevention of these parasites and the diseases they cause in ruminants. This review will be of interest to parasitologists, biologists, and veterinarians.
