The RIG ‐I receptors RIG ‐I, MDA 5 and LGP 2 are involved in viral recognition, and they have different ligand specificity and recognize different viruses. Activation of RIG‐I‐like receptors ( RLR s) leads to production of cytokines essential for antiviral immunity. In fish, most research has focused on interferons, and less is known about the production of proinflammatory cytokines during viral infections. In this study, we h...

Elucidation of the role of infectious agents putatively involved in gill disease is commonly hampered by the lack of culture systems for these organisms. In this study, a farmed population of Atlantic salmon pre‐smolts, displaying proliferative gill disease with associated Candidatus Branchiomonas cysticola, Ca . Piscichlamydia salmonis and Atlantic salmon gill pox virus ( SGPV ) infections, was identified. A subpopulation of...
