Abstract
Japanese eel endothelial cell-infecting virus (JEECV) causes viral endothelial cell necrosis of eel (VECNE), resulting in severe economic losses in eel aquaculture in Japan. Here, we report the complete genome sequences of two new JEECV strains isolated from farmed Japanese eels.

Japanese eel endothelial cell-infecting virus (JEECV) causes viral endothelial cell necrosis of eel (VECNE), resulting in severe economic losses in eel aquaculture in Japan
It is thought to be a chimeric virus between a polyomavirus and a virus of an unknown family, because the JEECV genome without the polyomavirus large T-like protein gene (LTLG) does not exhibit homology with any virus [2]
We detected JEECVs with a single amino acid change at the LTLG in Japanese eels with no symptoms and that are living in natural habitats [4]
Summary
Japanese eel endothelial cell-infecting virus (JEECV) causes viral endothelial cell necrosis of eel (VECNE), resulting in severe economic losses in eel aquaculture in Japan. Japanese eel endothelial cell-infecting virus (JEECV) is one of the most important viruses in the Japanese eel, Anguilla japonica (Temminck and Schlegel, 1847). JEECV causes viral endothelial cell necrosis of eel (VECNE) [1, 2], which is a lethal disease involving hemorrhage and congestion in the central venous sinus of the gills of farmed eels [3]. JEECV is a double-stranded circular DNA virus.
