  1. 1 Genes: PB2, PB1 and PA, polymerase genes; HA, haemagglutinin; NP, nucleoprotein; NS, non-structural proteins 1 and 2
  2. 2 Patristic distances; nucleotide substitutions/site. The isolate that gave the shortest distance for each gene is marked with an asterisk.
  3. 3 All five NS1 genes encode a slightly truncated (219 amino acids) NS1 protein as does the NS1 gene of S-OIV.
