a Knockdown (KD) of MGST1L, PGES2 and PGES3L in copepodids at 2 and chalimus 2 at 14 dpi. Expression level in KD lice were related to that of control lice (2−ΔΔCq ± SD, N = 4). Asterisk denotes significant KD compared to control lice. b–o mRNA level of selected immune genes in salmon (S. salar) skin infested with control and KD lice (L. salmonis). Skin was sampled 2 and 14 dpi at the site of lice attachment (infested) and in unaffected sites. The expression level was calculated as 2−∆∆Cq ± SD (N = 5) related to untreated control fish. Lowercase letters above bars indicate statistical significance from the untreated control fish (a) and from unaffected skin (b). p Salmon louse infestation success after KD, given as average number of lice/fish ± SD. IL Interleukin, TNF tumor necrosis factor, NCCRP non-specific cytotoxic cell receptor P, IFN interferon, CD cluster of differentiation, MHC major histocompatibility complex, Ig immunoglobulin, C complement
