Comparative study of the susceptibility to infection with Trypanosoma simiae of Glossina morsitans and G. tachinoides.

The susceptibility to infection with Trypanosoma simiae of Glossina morsitans and G. tachinoides was compared. A total of 592 G. tachinoides and 348 G. morsitans were used in trying to transmit T. simiae to pigs. G. morsitans were very good at transmitting T. simiae infection to pigs while G. tachinoides were very poor. The epidemiological importance of the results is discussed.
