Abstract:
The epithelial neoplasms were observed on the mouth of the cultured coho salmon, Oncorhynchus kisutch. Histopathologically, the tumors were formed to be proliferative epithelial cells, but no change was observed in other organs. The virus from this tumor was isolated in RTG-2 and CHSE-214 cells and developed the cytopathic effect which characterized to be the formation of syncytia and the migration of chromatin. This virus was neutralized with anti-Oncorhynchus masou virus (OMV) rabbit serum.
