In situ hybridization (mRNA) of gill sections collected from Atlantic salmon exposed to SGPV. Fish (from E.H group) injected intraperitoneally with hydrocortisone and exposed to SGPV 1 day after injection. In situ hybridization performed on gills sampled at A 3, B 7, and C 14 days after virus exposure showed a gradual increase in virus load and infected gill epithelium cells (in red) over the course of infection. Scale bar = 100 μm.
