Post-hoc comparisons showed significantly elevated production of GM-CSF (P = 0.005), IL-2 (P = 0.008), and IL-5 (P = 0.03) in the chronic infection compared to uninfected groups and elevated production of IL-5 (P = 0.03) and IL-10 (P = 0.0008) in the chronic versus light infection groups (Figures 1A–D). This evidence concerns the gene IL2 and infection.
