Coccidiosis is a disease related to what system?

Coccidiosis is a disease primarily related to the digestive system. This condition is caused by a parasitic infection from protozoa in the genus Eimeria, which predominantly affects the intestines of various animals, including birds. The parasites invade the intestinal lining, leading to symptoms such as diarrhea, weight loss, and in severe cases, can result in significant morbidity or even mortality. The association with the digestive system is crucial since the primary impact of coccidiosis is seen in the gastrointestinal tract, where the infections take hold and disrupt normal digestive processes.

The other options do not accurately relate to coccidiosis; for instance, the nervous system, vision, and plumage do not involve the specific symptoms or effects brought on by this disease, emphasizing the importance of understanding the gastrointestinal aspects of coccidiosis.
