AI Article Synopsis
- - The study aimed to identify genetic variants of the Tasmanian strain of Atlantic salmon aquareovirus (TSRV) using 14 isolates collected over 20 years from various host species in Tasmania.
- - Two main categories of TSRV variants, "typical" and "atypical," were established through initial genetic and physical analysis of these isolates.
- - Electron microscopy revealed at least three distinct variants based on viral particle size, and the research confirmed the presence of at least one new variant in farmed Tasmanian Atlantic salmon, separate from standard TSRV isolates.
Article Abstract
In an attempt to determine whether or not genetic variants of the Tasmanian strain of Atlantic salmon aquareovirus (TSRV) exist, 14 isolates of TSRV, originating from various locations in Tasmania, covering a 20-year period (1990-2010), obtained from various host species and tissues, and isolated on different cell lines, were selected for this study. Two categories, termed "typical" and "atypical", of variants of TSRV were identified based on preliminary genotypic and phenotypic characterization carried out on these 14 different isolates. In addition, electron microscopic examination indicated the existence of at least three variants based on viral particle size. Finally, this study demonstrated the existence of at least one new variant of TSRV isolates, other than the more commonly isolated typical TSRV isolates, in farmed Tasmanian Atlantic salmon.
