The two Trypanosoma brucei
subspecies that cause African trypanosomiasis, T. b. gambiense and T. b. rhodesiense, are
indistinguishable morphologically. A typical trypomastigote has a
small kinetoplast located at the posterior end, a centrally located nucleus,
an undulating membrane, and a flagellum running along the undulating
membrane, leaving the body at the anterior end. Trypomastigotes are the only stage found in patients. Trypanosomes
range in length from 14 to 33 µm.
