Abstract
SYNOPSIS The course of Trypanosoma congolense infections in Glossina morsitans morsitans was followed by electron‐microscopic examination of ultrathin sections of the guts and proboscises of infected flies. Guts dissected from flies 7 days after infection with culture procyclic forms of T. congolense had heavy trypanosome infections in the midgut involving both the endo‐ and ectoperitrophic spaces. Trypanosomes were also seen in the process of penetrating the fully formed peritrophic membrane in the central region of the midgut. By post infection day 21, trypanosomes had reached the proboscis of the fly and were found as clumps of epimastigote forms attached to the labrum by hemidesmosomes between their flagella and the chitinous lining of the food canal. Desmosome connections were observed between the flagella of adjacent epimastigotes. Flies examined at postinfection days 28 and 42 had, in addition to the attached forms in the labrum, free forms in the hypopharynx.Keywords
