Abstract Infectious salmon anaemia ISA is a highly fatal viral disease affecting marine-farmed Atlantic salmon which is caused by ISA virus ISAV a fish orthomyxovirus that has recently been assigned to the new genus Isavirus within the family Orthomyxoviridae. Mx proteins are among the interferon IFN -induced proteins responsible for the development of an antiviral state in vertebrate cells. We used real-time reverse transcription-polymerase chain reaction RT-PCR and Chinook salmon embryo CHSE-214 cells constitutively expressing Atlantic salmon Mxl protein ASMxl to examine the antiviral properties of ASMxI against two ISAV strains NBISA01 and HKS-36 having phenotypically different growth properties cytopathic vs non-cytopathic in the CHSE-214 cell line. We present evidence that ISAV is sensitive to ASMxl. CHSE-2l4 cells constitutively expressing ASMxl showed increased resistance to infection with the cytopathic ISAV strain NBISA0l .
