Eimeria is a genus of protozoa that are parasitic to many vertebrate animals, most often cattle, domesticated birds, goats, and sheep. These parasites contain an apical complexes and apicoplasts, organelles that allow the cell to enter a host organism. The life cycle of Eimeria is considered monoxenous, meaning that the cycle occurs in one host. The three stages of its life cycle include oocyst, sporozoite, and merozoite. They undergo both sexual and asexual reproduction during different stages of their life. Animals infected by Eimeria often develop the disease coccidiosis, which mainly causes diarrhea, fatigue, and loss of appetite. Coccidiosis is spread when an animal ingests infected tissue or is exposed to contaminated feces.[1]
