African Trypanosomiasis.

摘要

African trypanosomiasis is infection by protozoan hemoflagellates of the Trypanosoma brucei complex, subspecies of which cause disease in humans: Trypanosoma brucei gambiense causes Gambian (chronic) trypanosomiasis and Trypanosoma brucei rhodesiense causes Rhodesian (acute) trypanosomiasis. A third economically important subspecies, Trypanosoma brucei, causes nagana, a fatal disease of animals, but does not infect humans.
