Interpretive Summary: Agent, Infestation, and Diseases.Poultry and gamebirds are susceptible to several species of Eimeria, which cause an enteric disease characterized by diarrhea, morbidity, lost weight gain, dehydration, and sometimes mortality. Coccidia are intracellular parasites, often resulting in disruption of the intestinal mucosa as they reproduce. The life cycle is complex, but there are no intermediate hosts. Lateral and vertical transmission is by mechanical contamination with the reproductive forms (oocysts). Diagnosis. Diagnosis is by detection of characteristic gross iesions at necropsy and by detection of microscopic oocysts in fecal droppings. Interventions. Control is largely by prevention, using anticoccidial drugs in the feed or live vaccines administered at the hatchery.
