Veterinary medicine. 290 DISEASES OF THE Fig. 134.—Thin - necked bladder - worm (Cysti- tcnuicollis), with head extruded fi'om body, from cavity of a steer, natural size. (Stiles, Annual Report, Bureau of Agri- culture, 1901.) chiefly by a process of exclusion, though the signs furnished by percussion of the right flank, and by examination of the blood, are of some assistance. Prognosis. The prog- nosis is extremely grave. Treatment is of little value. Even supposing that the diagnosis has been exact, surgical intervention is out of the question, and only this would appear theoretically to offer a chance of success. The abscesses are multiple, deeply placed, separated from one another, and sometimes surrounded by enormous tracts of in- flamed tissue. In fact, the condition is of such a character as entirely to prohibit active measures. CYSTICERCOSIS. This disease is produced by the thin- or long- necked bladder-vorm {Gijslircrcus toudcuUis) found in cattle, sheep, and swine. The cysticercus represents an intermediate stage of de- veloijment of the marginate tapeworm {Ta'nia viarcji- nata) of dogs and wolves. It is by no means un- common in Europe and America, and occurs in the body cavity of cattle, sheep, swine, and other animals, attached to the diaphragm, omentum, liver, or other organ. When eaten by dogs or wolves, it develops into the marginate tapeworm, which was formerly confused with T. suUiim of man, and gave rise to the Pig. 136.—Head of the marginate tapeworm (Tania mairjinata).
