Short-term experiment showing bacteria population in Rhodnius prolixus midgut infected with Trypanosoma rangeli . Fifth instar nymphs were fed on inactivated blood containing 1 × 10⁶ epimastigotes/mL of T. rangeli. CFU counts were made 12 days after feeding. Bars represent mean ± SEM of three independent experiments with three pools of insects (n = 9). Each point represents the CFU from one pool of three insects. Means were compared using Student T-test or Mann–Whitney test; **p < 0.01.
