Figure 2. Antibacterial activity using inhibition zone (ZI) assay in Rhodnius prolixus 5^th-instar nymphs infected with Trypanosoma cruzi Dm28c clone.

(A) Antibacterial activity with anterior and posterior midgut regions at 9 days after feeding; (B) Antibacterial activity of anterior midgut at 5, 9 and 16 days after feeding. Bars represent mean ± SEM. Means were analyzed by using t Test and 1 way ANOVA. Each bar represents the mean (+/−SEM) of four separate experiment, n = 6−10 insects for each determination.
