【 摘 要 】

ABSTRACT: The nucleotide sequences of segments 2 and 8 of infectious salmon anaemia virus (ISAV) isolates from Scotland and Norway were determined and compared. Sequence variations were found in both segments, with segment 2 being more variable. Thesevariations were of the same degree as those found in previous comparisons of the first recorded strain of ISAV in Scotland and Norwegian strains for which sequence information was available. The sequences again demonstrate the separation of European andCanadian strains of ISAV but, as is expected for an RNA virus, reveal that the European ISAV is not homogeneous. These results demonstrate the value of nucleotide sequences as a tool for strain identification and epidemiological investigation of ISAV.
