Plasmodium infection inhibited the proliferation of tumor cells in colon cancer tissues. a Immunohistochemical staining demonstrates that the Ki67-positive cells were decreased in the CT26.WT + P.y group (×400). b The percentage of Ki67 expression in tumor tissues of the two groups (t-test, t₍₈₎ = 17.51, P < 0.0001). Brown areas represent positive expression. Scale bar = 50 µm. The results are shown as mean ± SEM (n = 5). ****P < 0.0001
