| 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． |
