Veterinary medicine. 68 Swine Erysipelas. circumscribed, round or more frequently quadrangular or rhom- boidal spots develop in various parts of the body, especially on the chest land back, outside of the thighs and on the neck, but sometimes over the entire body, which are warm to the touch and dark red or violet in color. Later they appear elevated above the surface of the surrounding skin as much as 2 to 3 mm. The center usually becomes pale while the border retains the bright color. In other cases the raised parts remain red and even become darker, while on their surface a serous fluid exudes, which raises the epithelium in the form of small vesi- cles which later dry to crusts. As a rule the plaques are of dollar size, but by their confluence swellings may be formed as large as the pahn of the hand. The development of the eruptions is usually associated with fever (up to 42.8° C), dullness, loss of appetite^ thirst.. Fig. 22. Sioine erysipelas. Gangrene of the skin of the back. (After Schwarzbart.) constipation, conjunctivitis, sometimes symptoms of paralysis and nausea. After the development of the eruptions the symp- toms diminish. Soon afterwards the eruptions also disappear, and after 2 to 3 days, sometimes however only after 8 to 12 days, the animal recovers. In some of the cases the changes in the skin take on a malignant character. On the parts of the body mentioned, more frequently, however, on the ears, head and tail, the skin swells considerably in certain spots, becomes dark red and warmer; soon these places become insensitive, cooler and dry, and finally become separated from the surrounding and , underlying tissues, or the animal loses one or both ears, its tail or distal digits. Sometimes the inflamed skin over the back dies off in its entire extension so that it covers the upper part of the body in the form of a shield (Fig. 22), and gradually loosens from the borders and
