Vaccines of WCA formulated with AH, but not with AP or vaccines without adjuvants induced an IL-17 response. IL-17 concentration in the supernatant of whole blood cultures incubated for 6 days with WCA (107/mL). The blood was collected from mice injected three times with WCA, WCA/AH or WCA/AP at 106 cells/dose, 107 cells/dose or 108 cells/dose. The bars indicate the mean ± SEM of 8 mice per group. * p < 0.05; ** p < 0.005 (WCA/AH vs. WCA and WCA/AH vs. WCA/AP).
