Comparison of complete polyprotein sequences of two isolates of salmon alphavirus (SAV) type I and their behaviour in a salmonid cell line

Comparison of complete polyprotein sequences of two isolates of salmon alphavirus (SAV) type I... Salmon pancreas disease virus is an alphavirus (family Togaviridae ) affecting mainly Atlantic salmon ( Salmo salar L.). Both polyprotein sequences of the Scottish isolate (SAV4640) were determined and compared with those of Irish isolate SAVF93-125. High amino acid sequence similarity (99.4 %) was found. Six amino acid deletions were found in the E2 gene of SAV4640. SAVF93-125 demonstrated a high viral load in culture despite high Mx expression. Approximately 50 % of cells infected with SAVF93-125 exhibited a cytopathic effect by day 8. SAV4640 successfully entered the cells, inducing 10,500-fold higher Mx expression at day 2 compared to SAVF93-25; however, no replication was observed based on results of the nsP1 qRT-PCR. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals
