Neutralization of IL-17 resulted in a apparent increase of bacterial colonization in vivo. MntC-vaccinated mice (n = 5) were intraperitoneally injected with anti-IFN-γ or (and) anti-IL-17, infected non-lethal dose S. aureus Newman 2 days later. One day post-infection, the mice were sacrificed, their (A) blood, (B) spleens, (C) kidneys, (D) lungs and (E) livers were harvested and homogenated to measure the CFUs of bacterial colonization. Mice immunized with MntC did not obtained a apparent protection to eliminate bacteria in mice, when the biological activities of IL-17 was inhibited. The CFUs of bacterial colonization in non-vaccinated mice and vaccinated without neutralizing cytokines mice were considered as the control groups, respectively. Significant differences were indicated by (*P < 0.05), (**P < 0.01) and (***P < 0.001).
