Figure 1.

Serum concentrations of cytokines during experimentally induced swine dysentery. Serum concentrations of IL-1β, TNF-α and IL-10 before inoculation, during clinical signs of dysentery, and during the recovery period are shown by the box plot. The shaded circles illustrates the individual values of the two animals that remained clinically healthy sampled before inoculation and at days 4, 14, 21, 28 and 35 post-inoculation. The shaded areas above zero represent the detection limit of the assays. * significantly different from the pre-inoculation value.
