Validation of a TaqMan one-step real-time RT-PCR assay targeting ISAV segment 7 spliced mRNA.

Infectious salmon anaemia virus (ISAV) can cause severe systemic infection in Atlantic salmon (Salmo salar L.), and a timely diagnosis is critical. Conventional real-time reverse transcription PCR (RT-qPCR) assays target unspliced RNA from either ISAV segment 7 or 8 and provide data on viral load.
