The spirochaetes are found during the pyrexia. Tangles are numerous. Death takes place in four to five days. The spleen and liver are much enlarged. The disease is conveyed by ticks of the genus Argas. When , inoculations are made spirochaetes do not appear in the blood until the second day. They then increase until the fifth or sixth day, when they suddenly disappear. 4. Spirochaete theilevi.—In cattle in Transvaal and Cameroons.
