Transcriptome analysis of Atlantic salmon (Salmo salar) skin in response to sea lice and ISAV coinfection under different functional diets

In this study, transcriptomic analysis was used to evaluate the impact of four experimental functional feed diets (i.e. control = 0.3% EPA/DHA+high-omega 6, Ctrl+IS = 0.3% EPA/DHA+high-omega 6+ immunostimulant, FA+I = 1% EPA/DHA + high-omega 6, and FA-I = 1% EPA/DHA + high-omega 3) on Atlantic salmon (Salmo salar) during a single infection with sea lice (L. salmonis) and a co-infection with sea lice and ISAV. The overall objectives were to compare the transcriptomic profiles of skin between single and co-infection groups, and to assess differences in gene expression response among animals with different experimental diets.
