There were no significant changes in the secretion of the type II cytokine IL-4 (Figures 5B,I), but type II cytokine IL-5 (Figures 5C,I) was increased post-infection; the RH group had lower IL-5 levels than the ME49 group at day 5 and 9 post-infection (Figures 5C,I). This evidence concerns the gene IL5 and infection.
