Abstract: Pathogenicity of 6 strains of salmonid helpesvirus 2 (SaHV-2) isolated from kokanee salmon, masu salmon, coho salmon and rainbow trout in Japan against 1-month-old maw salmon was compared with immersed artificial infection. Cumulative mortality of masu salmon infected with six SaHV-2 strains ranged 50 to 71%, and no severe difference was observed. Cumulative mortality of the control group was 4% during 60 days.
日本のサケ・マス由来のヘルペスウイルス(Salmonid Herpesvirus-2 : SaHV-2)の代表株6株を用い,同―条件下でサクラマスの浮上稚魚に対する病原性を比較検討した.感染実験に供試したウイルスの継代数はサクラマス由来のOMVのみが16代であったが,RKVは4代,NeVTA,YTV,CSTV,COTVは5代であった.10^2.75から10^3.50TCID50/Lに調整した各ウイルスを用い,1時間浸漬攻撃し,2ケ月間流水飼育し経過を観察した.その間の累積死亡率はYTV が71%,RKV が69%,COTV 55%,CSTV が54%,0MVが51%,NeVTAが50%となり,多少の差は認められたが,全体として明白な違いは観察されなかった.
