Pairwise comparisons of the NS1 sequences of selected human influenza A viruses and vaccine virus strains.

Figures in italic represent aligned NS1 nucleotide sequences and figures in boldface represent aligned NS1 amino acid sequences. All alignments were done using the Needleman-Wunsch algorithm and the values indicate identity percentages. Full names of the strains are as follows: A/Finland/554/2009; A/California/07/2009; A/USSR/90/77; A/Singapore/6/1986; A/New Caledonia/20/99; A/Brisbane/59/2007; A/Udorn/72; A/Bangkok/01/1979; A/Sichuan/02/87; A/Moscow/10/99; A/Brisbane/10/2007.
