IFN-γ and IL-10 quantifications in BALF. A IFN-γ level was quantified in BALF using ELISA. B IFN-γ and C IL-10 gene expressions were measured in BALF cells by RT-PCR. The presented values are the relative expressions calculated from the cycle threshold (Ct) results on each post-infection day as a function of those obtained the day before the infection as described in “Materials and methods” section. All data are reported as the mean (±SE) of results obtained for the pigs in the Control or Finistere group (n = 5 in each group) or the surviving pigs (n = 5–8) in Lena group. “a” indicates a significant difference between the Control and Lena groups, “b” a significant difference between the Control and Finistere groups and “c” a significant difference between the Lena and Finistere groups using a global Kruskal–Wallis test followed by a Holm’s adjusted pairwise Wilcoxon-Mann-Whitney test (p < 0.05).
