Long-term experiment showing bacteria population in Rhodnius prolixus midgut infected with Trypanosoma rangeli . CFU counts were made with R. prolixus 5^th instar nymphs 12 days after feeding (DAF) on blood without parasites. Previously, 4^th instar nymphs were fed on inactivated blood with or without 1 × 10⁶ epimastigotes/mL. Bars represent mean ± SEM of three independent experiments. Each point represents the CFU from three pools of three insects (n = 9). Means were compared using Student T-test or Mann–Whitney test; **p < 0.01 and *p < 0.05.
