Immunopathological Aspects of Experimental Trypanosoma cruzi Reinfections
(a) Survival curve of reinfected mice, , Log-rank test. (b) Parasitaemia of mice that were primarily infected and reinfected with the Colombiana and Y strains of T. cruzi. Parasitaemia levels were evaluated by counting the number of parasites in 5 μL of blood collected from the tail vein. The symbols of each group represent the mean. differences in animals primarily infected with the Colombiana strain or Y strain were analyzed on Days 7, 14, and 21; Mann-Whitney test. #Statistical differences among the reinfected groups (Y/Y, Y/Col, Col/Col, Col/Y) were analyzed on Days 7, 14, and 21; Kruskal-Wallis test.
