Figure 2From: Humoral responses in Rhodnius prolixus: bacterial feeding induces differential patterns of antibacterial activity and enhances mRNA levels of antimicrobial peptides in the midgutAntibacterial activity of the anterior midgut contents of Rhodnius prolixus on different days after feeding. A- Activity of anterior midgut contents against E. coli. B- Activity of anterior midgut contents against S. aureus. Antibacterial activity detected by turbidometric assay (TB) (OD550 nm) after 19 h incubation of anterior midgut content samples with different bacteria. Values represent the means ± SD of 9 pools using 3 insects each (n = 27) in triplicate wells. Asterisks relate to significant differences (*p < 0.05, **p < 0.01, ***p < 0.001) obtained after data were compared to day seven using one way ANOVA and Mann Whitney tests.Back to article page
