Avermectin treatment for Lepeophtheirus salmonis: Impacts on host (Salmo salar) and parasite immunophysiology. Avermectin treatment for Lepeophtheirus salmonis: Impacts on host (Salmo salar) and parasite immunophysiology

This study investigates the transcriptomic responses of salmon lice (L. salmonis) infecting salmon treated with emamectin benzoate (either 1x or 3x), ivermectin, or commercial feed controls Overall design: Copepodid-staged larvae of L. salmonis were used to infect Atlantic salmon fed 1x or 3x emamectin benzoate, ivermectin, or commercial feed controls. Pre-adult I lice were collected from each group, pooled by treatment group and sex (pools of 6 lice) and stored at -80C for RNA extraction and microarray analyses. A total of 48 pools were used (n = 6 per condition except n = 5 for male controls and n = 7 for male 3xEMB)
