Figure 7From: First record of experimentally induced salmon gill poxvirus disease (SGPVD) in Atlantic salmon (Salmo salar L.)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.Back to article page
