Microscopic examination of the manure is needed to confirm the parasite. Treatment of outbreaks is most effective if begun early. Animals showing signs of the disease should be isolated from healthy animals. Drugs that have been used to control outbreaks include amprolium, sulfaquinoxaline, decoquinate and monensin. Intravenous administration of fluids is sometimes warranted in cases of severe diarrhea and blood loss.
Mild outbreaks are usually self-limiting.
To prevent outbreaks, reduce overcrowding and other stresses. Raising feed bunks and water troughs will also minimize the risk of massive exposure through manure contamination. Severely affected animals should be removed and not reintroduced until they have recovered. Healthy animals will usually develop immunity to coccidiosis through moderate exposure. Controlling losses from coccidiosis lies in proper animal management, constant surveillance, early, accurate diagnosis and prompt treatment when indicated.
