Abstract
Seven strains of Oncorhynchus masou virus (OMV) genomes were analyzed with the restriction endonucleases BamHI, EcoRI, HindIII and SmaI. The restriction patterns of OMV strain DNAs were divided into four groups. Restriction profiles of high passage strains (00-7812, 65th passage, and H-83, 60th passage) were different from those of low passage strains (00-7812, 8th passage, and H-83, 6th passage) when digested with BamHI, HindIII and SmaI. However, no difference was observed between the restriction patterns of high and low passage viral DNA with EcoRI. There was no distinct difference observed between the restriction patterns of tumor tissue-derived and coelomic fluid-derived strains. By using 32P-labelled DNA of standard OMV (strain 00-7812) as a probe, most of the fragments of other OMV strain DNAs were hybridized.
