Genetic comparison of viral hemorrhagic septicemia virus isolates from North America and Europe
Viral hemorrhagic septicemia virus (VHSV) is the cdusative agent of a serious rhabdoviral d~sease of rainbow trout Oncorhynchus myklss in Europe The first isolation of the vlrus in North Amenca occurred In the fall of 1988 when it was recovered from adult chinook 0 tshawytscha and coho 0 klsutch salmon returning to 2 hatcher~es in the state of Washington, USA The following year, VHSV was isolated from adult coho salmon at 2 other hatcher~es in northwestern Washington In 1990 and 1991, VHSV was recovered from Pacific cod Gadus macrocephalus caught in Pnnce Willlam Sound, Alaska Genetic vanation among the 4 isolates from salmon and the 1990 ~solate from Pacific cod was determ~ned uslng T1 nbonuclease finqerprlnt~ng In addition, 4 d~verse isolates from Europe were lncluded for companson The North Amencan isolates of VHSV formed a slngle fingerprint group In which the 4 isolates from salmonids were h~ghly similar to each other and the isolate from Pacific cod was related but less s~milar The 4 European ~solates which included an isolate from Atlantic cod G morhua, formed a second fingerpnnt group The genetic d~vers~ty among the isolates within each fingerpnnt group was estimated to be less than 5 % whlle the North Amencan and European strains of the virus were judged to differ by more than 5% The results indicate that the North Amerlcan isolates of VHSV are not of European ongln and that the virus may be enzootic wlthin the manne environment.
