The development of Trypanosomes in tsetse flies

Abstract

In the 'Proceedings,' of the Royal Society (B, vol. 81, 1909) a paper was published describing a single experiment illustrating the development of Trypanosoma gambiense in Glossina palpalis This experiment was carried out at Mpumu, Uganda, near Lake Victoria, in the spring of 1909. Since that date many experiments, on the same lines, have been made, not only with Trypanosoma gambiense but also with Trypanosoma dimorphon, Trypanosoma nanum , and Trypanosoma vivax . It is proposed to describe these further experiments in this paper. It will be remembered that Kleine, in German East Africa, at the end of 1908, made the discovery that Glossina palpalis could convey Trypanosoma brucei for some 50 days after the fly had fed on an infected animal. Following Kleine’s lead, our experiments were carried out, at first with Lake-shore flies, afterwards with flies bred in the laboratory.
