Surveillance of salmonid viruses especially targeting infectious salmon anemia virus in Japan
Infectious salmon anemia (ISA) is a virus disease of Atlantic salmon Salmo salar in Europe and the Americas, but it has not been isolated in Far East Asia. In this study, we conducted virus isolation with ASK and ASE cells targeting ISA virus (ISAV) from a total of 5,967 fish belonging to eight salm...

Summary: | Infectious salmon anemia (ISA) is a virus disease of Atlantic salmon Salmo salar in Europe and the Americas, but it has not been isolated in Far East Asia. In this study, we conducted virus isolation with ASK and ASE cells targeting ISA virus (ISAV) from a total of 5,967 fish belonging to eight salmonid species in Japan from 2005 to 2007. ISAV was not isolated from any fish examined but infectious hematopoietic necrosis virus was isolated from 116 fish belonging to three species, while infectious pancreatic necrosis virus was found in 14 fish from three species. It was considered that Japan is still free from ISAV. 伝染性サケ貧血症ウイルス(ISAV)の浸潤状況を明らかにすることを目的に、2005〜2007年にかけてサケ科魚類8種5,967尾のメス親魚から体腔液を採取し、ASKおよびASE細胞を用いてウイルスの分離培養を試みた。その結果、ISAVはいずれの検体からも分離されなかったが、3魚種116尾から伝染性造血器壊死症ウイルス(IHNV)が、また3魚種14尾から伝染性膵臓壊死症ウイルス(IPNV)が分離された。従って、ISAVは日本未侵入であると考えられた。 |
