Résumé
Using green fluorescent protein as a reporter, we have shown that the strain 29–13 of
Trypanosoma brucei, widely used for inducible down-regulation of mRNA, is inducible in, but not permissive for the tsetse flies
Glossina palpalis gambiensis and
Glossina morsitans morsitans. Within two weeks post-infection, 42% males and females of teneral and non-teneral tsetse flies harboured intestinal infections, yet not a single infection progressed into the salivary glands.
