Stabilityof nine Viral Haemorrhagic Septicaemia Virsus (VHSV) isolates inseawater

P.F. Dixon

Nine VHSVisolates, comprising three from marine hosts from North America, threefrom marine hosts from Europe, and three fromfreshwater rainbow trout from Europe were compared for their stabilityin seawater at four different tempera-tures. There was an inverse correlationbetween survival and temperature for all isolates; survival at 4 °Cwas for longer than at 20 °C. There was variation in survival timesbetween the different isolates. One of the isolates from freshwater rainbowtrout was the most stable in seawater (persisting for between 28 and35 days at 4 °C), but another of those iso-lates was the least stablein seawater (persisting for between 3 and 7 days at 4 °C). The stabilitiesof the North American and European isolates from marine fish were quitesimilar to each other. Survival of those isolates was for between 7 and21 days at 4 °C.
