The epidemiology of Trypanosoma rhodesiense sleeping sickness in Alego Location, Central Nyanza, Kenya. II. The cyclical transmission of Trypanosoma rhodesiense isolated from cattle to a man, a cow and to sheep.

Abstract Succesful cyclical transmission was achieved through Glossina morsitans of a strain of T. rhodesiense isolated from a cow in Alego to a man, a cow and sheep. The importance of a reservoir of T. rhodesiene in cattle in which no clinical symptoms occur and where the causative organism is resistant to the drug normally used to treat cattle trypanosomiasis in the area is discussed.
