Enhanced antigen-specific IL-17 and IFN-γ production in mice infected with ΔbscN B. pertussis (BP) 12743. BALB/c mice were challenged with an aerosol of WT or ΔbscN B. pertussis 12743. Spleen cells recovered 14 (A and C) and 21 (B and D) days postchallenge were stimulated with sonicated B. pertussis 12743 (Bp), FHA, PT, or medium (Med) only as a control. Supernatants were removed after 3 days, and IL-17 (A and B) and IFN-γ (C and D) concentrations were determined by ELISA. *, P < 0.05; **, P < 0.01; ***, P < 0.001 (ΔbscN versus WT).
