THE PARASITES OF THE PIG. A.—Parasitic Worms. measle worm.— Cysticercus cellulosus. This is the larval form of the broad tape worm of humans, Tae-nia solium. The cysts or nodules are about i inch diameter, yel-lowish white in color, and may sometimes be discerned with thenaked eye, but usually the microscope is required. These cysts are 130 N. C. AGRICULTURAL EXPERIMENT STATION. most commonly found in the muscles or lean meat of the neck,shoulders and tongue, and least common in the hams and back. They are rarely found in the kidneysand lungs (Fig. 19). The para-site finds entrance to the hog bythe latter drinking water pollu-ted by sewage, or eating herbageor something soiled by excre-cment of a person harboring atape-worm. It is estimated thata man harboring a tape-wormmay give off in the course of ayear 250,000 eggs, each capableof developing a worm. The dog,cat, in fact any carniverous orgarbage eating animal may alsobecome infested by this humans occasionally har-bor it in both the larval and ma-ture conditions. The pig, how-ever, above all animals, is mostexposed to infestation in the lar-val conditions, and all breedsseem about equally liable.
