Expression of innate antiviral genes in blood cells in challenge experiment #2.

<p>Relative expression of type I interferon (IFNab) (A) and Mx (B) in controls (grey), the PRV-High (red) and the PRV-Low (green) group (n = 6). Target Ct values are normalized against the expression level of elongation factor (EF)1α, and fold induction relative to the mean level of control fish (0 wpc) is shown. Statistical analysis comparing PRV-High and PRV-Low was performed using Mann-Whitney test at each time point, *p < 0.05, asterisk color (red and green) indicate the significantly higher group.
