The rainbow trout, Salmo gairdneri, gonad (RTG-2) cell line was more sensitive to lytic infection by infectious pancreatic necrosis virus (IPNV) than was the fathead minnow, Pimephales promelas, (FHM) cell line in laboratory and field studies. Laboratory investigations with known strains of IPNV (VR 299 and Buhl) also indicated that the cytopathic response in IPNV-infected chinook salmon, Oncorhynchus tshawytscha, embryo (CHSE-214) cells was greater than in infected FHM cells. In contrast, titration experiments with standard infectious hematopoietic necrosis virus (IHNV) isolates (Oregon and Cedar River) showed that the FHM cells were more sensitive to destructive infection by IHNV than was either of the salmonid cell lines (RTG-2, CHSE-214). Key words: fish cell culture, infectious pancreatic necrosis virus, infectious hematopoietic necrosis virus, chinook salmon embryo cells, fathead minnow cells, rainbow trout cells, salmonid viruses

Pancreatic Necrosis Virus

Co-infection is an infection of more than one pathogen. In aquatic environment, the most common occurrence is appearance of infectious pancreatic necrosis virus (IPNV) in the presence of other viruses such as infectious hematopoietic necrosis virus (IHNV), viral hemorrhagic septicemia virus (VHSV), infectious salmon anaemia virus (ISAV), or salmonid alphavirus (SAV). In most cases, the IPN virus reduces the proliferation of other viruses in cell cultures or in the internal organs of salmonids, for example in IHNV or ISAV co-infections. However, it happens that there is no significant effect on the multiplication of the virus with which it coexists, e.g. IPNV-VHSV. Body's defense mechanisms, interferon and other interferon-like factors or mutations in the genome play an important role in co-infection..
