Genomic organization of infectious salmon anaemia virus
The RNA genome segment order, nucleotide sequence and the putative encoded proteins were determined for infectious salmon anaemia virus (ISAV). Eight segments of genomic viral RNA between 1�0 and 2�4 kb in length were identified. RNA segments 1–6 each had a predicted single open reading frame encodi...

The RNA genome segment order, nucleotide sequence and the putative encoded proteins were determined for infectious salmon anaemia virus (ISAV). Eight segments of genomic viral RNA between 1�0 and 2�4 kb in length were identified. RNA segments 1–6 each had a predicted single open reading frame encoding the P1, PB1, NP, P2, P3 and HA proteins, respectively. Segment 7 encoded the P4/P5 proteins and segment 8 encoded the P6/P7 proteins. Seven virion proteins with molecular masses between 25 and 72 kDa were found by SDS–PAGE analysis. The 72 and 42 kDa proteins were immunoreactive with ISAV antiserum from Atlantic salmon. The molecular mass of the 72 kDa virion protein suggested that it was the NP protein encoded by segment 3.
