a
The numbers in brackets are the GenBank accession numbers for the reference virus sequences. The numbers in parentheses are the references for each sequence. Note that all influenza virus lineages were avian.
b
The full-length protein-coding region of the NA gene of Sw/ONT/99-1 was determined in this study. However, this analysis was restricted to the 5′-most (in mRNA sense) 277 nucleotides, because only partial N6 sequences are available in GenBank.
