Geometric means of cytokine levels: (A) IL-10, (B) IL-12p70, (C) TNF, (D) IFN-γ, (E) IL-17.

<p>Cytokine levels in pg/mL after stimulation with 5×10⁷ inactivated bacteria/mL of PBMCs from six healthy blood donors are shown. IL-10, IL-12p70 and TNF were measured after a 24 h stimulation; IFN-γ and IL-17 after five days of stimulation. Geometric means and 95% confidence intervals are shown. F) <b>Arithmetic means of cytokine levels.</b> The arithmetic mean of the cytokine level (pg/mL) for each individual isolate is shown. M avium a = <i>Mycobacterium avium avium</i>; M avium h = <i>Mycobacterium avium homunissuis</i>; No Bact = no bacteria; G+ = <i>Streptococcus mitis</i>; G− = <i>Escherichia coli</i>. Note that Figure F is shown on a logarithmic scale.
