SPIROCHAETOSIS IN MAMMALS 311 to the fowl did not transmit the disease. In 1906, Stordy observed the spirochete in the Abyssinian pony. The animal was dull, hanging head, large swellings over the orbits and acute edema of the neck. The temperature was 97° F. The next day the edema had disappeared about the head, the temperature had fallen to 95° F, while on the third day rapid emaciation had begun, edema between the legs and under the abdomen became persistent, and the temperature rose to 99° F. On the fourth day spirochetes were found in the blood and edematous fluid. The tick Rhipicephallus pulchellus was found on the animal as it was common to cattle, horses, dogs and game in the district. There was suspicion of its being a carrier. He does not give evidence to prove that this was the case. In 1905, Jowett found a spirochete varying from 7 to Wv- or more in length by [a in breadth in cases of cancre and grease of the horse. In this connection it should be stated that spirochetes have been found in ulcerous processes in man, in the venereal granu- lomata of the bitch, the carcino- mata of the mouse and in granular and ulcerating suppurating wounds in other animals. But the relation of these organisms to the lesions with which they are associated has not been de- termined. Jowett, however, found the spirochetes in practi- cally every case that he ex- amined. Spirochaetosis in swine. In 1906, Dodd described a spirochete which he found in a pig sent to the Government laboratory in Pretoria. The examination showed very few morbid changes in the tissues but the skin was sprinkled with dark hemorrhagic-like spots. From scrapings of these lesions he was able to find the organism. It was not discovered in its blood. The spirochetes disappear from the lesions very soon a
