Coccidia of the genus Eimeria are single-celled obligate intracellular parasites that develop and multiply in the host’s intestinal epithelium. Sporulated coccidia oocysts, when ingested by the host, initiate an infection cycle that causes damage to the intestinal architecture, resulting in reduced feed utilization, impaired nutrient absorption, poor growth, high mortality, and an increased susceptibility to other diseases such as necrotic enteritis
