Phylogenetic analysis of the NS gene. Phylogenetic analysis of the NS gene (nucleotides) of seasonal influenza A (H1N1/H3N2) strains circulating in eastern India with respect to allele A and allele B gene pool [A/mallard/Gloucestershire/PD374/1985(H10N4) and A/Mallard Duck/ALB/302/1977(H10N7)], concurrent vaccine and other worldwide strains during 2007-2009 was carried out taking B/Lee/40 as an out-group. The tree was created by using neighbor-joining method and bootstrapped values of ≥70% were given for each node. The 2007 and 2009 A/H1N1 eastern India strains with A/Puerto Rico/8/1934(H1N1)-like NS gene are highlighted (♦).
