Etymology: Cyathostominosis is a modern medical coinage built from Greek and Latin parts, so it has no ancient history of its own. Its core is "Cyathostomum," the name of a genus of small nematode worms, which is itself formed from the Greek "kyathos," meaning "cup," and "stoma," meaning "mouth." The reference is to the cup-shaped structure these worms use to attach to the lining of the intestine. The ending "-osis" is a standard medical suffix for a diseased or abnormal condition, so the whole word literally means a condition caused by Cyathostomum worms. The name therefore describes the parasite's anatomy rather than the symptoms. Veterinarians use it for the disease that these small strongyles cause in horses, particularly in the large intestine and cecum, where the worms burrow into the wall and can provoke inflammation and diarrhea.

Synonyms: small strongyle infection, cyathostome infection
