Description
Summary:Artículo de publicación ISI The infectious salmon anemia virus (ISAV) is a severe disease that mainly affects the Atlantic salmon (Salmo solar) aquaculture industry. Although several transcriptional studies have aimed to understand Salmon-ISAV-interaction through the evaluation of host-gene transcription, none of them has focused their attention upon the viral transcriptional dynamics. For this purpose, RNA-Seq and RT-qPCR analyses were conducted in gills, liver and head-kidney of S. salar challenged by cohabitation with ISAV. Results evidence the time and tissue transcript patterns involved in the viral expression and how the transcription levels of ISAV segments are directly linked with the protein abundance found in other virus of the Orthomyxoviridae family. In addition, RT-qPCR result evidenced that quantification of ISAV through amplification of segment 3 would result in a more sensitive approach for detection and quantification of ISAV. This study offers a more comprehensive approach regarding the ISAV infective process and gives novel knowledge for its molecular detection. FONDAP (CONICYT-Chile) 1510027 - CORFO INNOVA 09-MCSS6682
