¹Values above the diagonal are nucleotide sequence identities (%); values below the diagonal are deduced amino acid sequence identities of Outer clamp (σ3) protein (%). Bold text denotes sequence identities among sub-genotype Ia PRV strains.
*Denotes Norwegian PRV “isolates” from Atlantic salmon farms at different points in the life cycle from pre-smolts to fish ready for slaughter [29], available in GenBank Accession Numbers JN991006 (isolate 5433), JN991012 (isolate 3817), JN991007 (isolate 1921), JN991008 (isolate 9326), JN991011 (isolate 8286), JN991010 (isolate 7030), and JN991009 (isolate 7243). PRV isolate Salmo/GP-2010/NOR is the Norwegian PRV sequenced on all 10 genomic segments; its segment S1 sequence is GenBank Accession Number GU994022.
The Chilean PRV sequences 8857 and 337 have inserts relative to the other strains, contributing to the lower sequence identities with other strains.
