Fig. 1 — Bacteria populations in the Rhodnius prolixus midgut infected with Trypanosoma cruzi. Colony forming units (CFU) were counted in the anterior and posterior midgut samples seven days after feeding the insects with blood at a final concentration of 1 × 10⁷ epimastigotes/mL. Insect treatments: black columns-control insects (C); grid columns-T. cruzi Dm 28c clone-infected insects (Dm 28c); striped columns-T. cruzi Y strain-infected insects (Y). Bars represent the mean ± SEM of three independent experiments with nine pools of insects (n = 9). Means were compared using Student’s T-test or Mann—Whitney test; *** p < 0.001, * p < 0.05
