A common adult tapeworm of the human, has its larval or cyst stage in the flesh of the hog, causing what is called "measly ; The adult tapeworm constantly forms new segments back of the small head. These segments ma- ture while new segments are being added in front of them. The terminal segments, filled with eggs, separate and pass off with the manure, while the head remains attached to the mucous membrane and continues to produce new segments. The injury to the host may be great or slight depending on the location—usually in the intestine —and number of worms. The worms may impair intestinal capacity and function by mere presence in large numbers. They may enter bile ducts and cause serious trouble. Some species have heads armed with hooks which irritate the intestine and thus im- pair digestion and absorption. They may produce and free to the intestinal contents, toxins or poi- sons. The cyst stage may seriously disturb the invaded host organ, , the brain as in gid. Treatment1 can be useful only when given before weakness begins. Preparation for treatment is most important. Allow no dry bulky food for several days. Past 12 to 24 hours, depend- ing on age and previous feed. Then give 1 to 2 drams freshly ground areca nut in a small feed such as damp bran, or in a small quantity of thin sirup, so that each sheep gets its proper dose. Copper sulphate used as for stomach worms (see Lec- ture XXX) is also a satisfactory treatment, and may be used for both parasites at the same time. Follow this treatment in 3 or 4 hours by a physic. 1 For sheep. Dose varies greatly with age and Fig. 49.—A Common Tapeworm op Sheep (Curtice.)
