Fig. 2From: The role of the peritrophic matrix and red blood cell concentration in Plasmodium vivax infection of Anopheles aquasalisEffect of exogenous chitinase and trypsin enzyme inhibitor on the infection of Anopheles aquasalis with Plasmodium vivax. The intensity of infection of each experimental group is presented in the top graph as the oocyst number per midgut (dots), the black lines represent the mean (Kruskal-Wallis H-test: χ2 = 41.333, df = 3, P < 0.0001). The infection rate is represented in the bottom graph as the percentage of P. vivax infected mosquitoes (light blue pie section) (ANOVA: F(3, 8) = 10.63, P = 0.0036)Back to article page
