qPCR validation study for catalase and Glp1_v2 genes in the louse groups Ls A-2013 (white circles), Ls V-2013 (grey circles), Ls A-P0 (white triangles) and Ls V-P0 (grey triangles). Ls A represent the sensitive lice, and Ls V, the resistant lice. Solid lines represent the arithmetic mean in each group. Data shown as fold change (log2^{−(∆∆Cq)}) referred to Ls A (Ls A-2013 and Ls A-P0) (calibrator sample). Statistical analysis was not performed due to the low sample size in some of the groups
