Coenurosis

Coenurosis (a.k.a. Caenurosis and Coenuriasis, gid or sturdy in the vernacular) is a parasitic infection that develops in the intermediate hosts of some tapeworm species (Taenia multiceps, T. serialis, T. brauni, or T. glomerata) and are caused by the coenurus, the larval stage of these worms. This disease occurs mainly in sheep and other ungulates, but occasionally can occur in humans too by accidental ingestion of worms' eggs.
