. The morphology of Blastocrithidia triatomae , when colonizing the rectum of Triatoma infestans , was studied by scanning electron microscopy. The posterior end of the epimastigote's body is tapered and often rolled up. The “straphangers” (cyst stages) are connected with the flagellum by “cytoplasmic bridges”; after “straphanger” detachment these bridges persist as remnants. A comparison of colonization densities of B. triatomae and Trypanosoma cruzi shows that both prefer to colonize the rectal gland, but minor density differences are apparent for B. triatomae in other rectal regions. The colonization density in established infections of B. triatomae is always greater than that of T. cruzi , especially near the midgut exit.
