A sensitive non‐destructive method for detecting IPNV carrier Atlantic salmon, Salmo salar L., by culture of virus from plastic adherent blood leucocytes
Abstract In populations of Atlantic salmon in sea water, infectious pancreatic necrosis virus (IPNV) could be detected by standard virological culture methods in sonicated kidney homogenates and in mucus samples (gill, skin and rectum) from 14 and nine of 25 fish, respectively, but all fish were pos...
