| Abstract: | Aquabirnaviruses, represented by Infectious pancreatic necrosis virus (IPNV), have been isolated from epizootics in salmonids and a variety of aquatic animals in the world; six genogroups of aquabirnaviruses have been identified. In comparisons of nucleotide sequences of the VP2/NS junction region, maximum nucleotide diversities of 30·8 % were observed among 93 worldwide aquabirnavirus isolates. A phylogenetic tree revealed the existence of a new genogroup, VII, for Japanese aquabirnavirus isolates from marine fish and molluscan shellfish. Nucleotide diversities between genogroups VII and I–VI were 18·7 % or greater. At the nucleotide level, Japanese IPNV isolates from epizootics in salmonids were nearly identical to a genogroup I strain from the USA or Canada. It is suggested that Japanese IPNV isolates belonging to genogroup I were originally introduced from North American sources, whereas Japanese aquabirnavirus isolates of genogroup VII were from marine aquatic animals indigenous to Japan. |
