FIG. 1.

Differences in median cytokine levels in the test mice and the control mice (in pg/100 mg tissue), where the median control levels are zeros on the y axis. (A) TNF-α, IFN-γ, IL-1β, and IL-2; (B) IL-4, IL-6, and IL-10. Each bar represents the values for four test mice compared to the values for four control mice at that time point. Black bars, white bars, and bars with slanted black lines, data for day 1, day 3, and day 5 postinfection, respectively (*, P < 0.05, Mann-Whitney U test). Error bars represent ranges (maximum or minimum test value minus median control value).
