*PB, basic polymerase; PA, acidic polymerase; HA, hemagglutinin; NP, nucleoprotein, NA, neuraminidase; M, matrix; NS, nonstructural; A, genes with closest homology to European avian-like swine influenza viruses (H1N1); H, genes with closest homology to European swine influenza viruses (H1N2); ND, gene not sequenced but typed as N2 by using standard NA inhibition assay; P, genes with closest homology to pandemic (H1N1) 2009 virus. Closest matching homologous genes were determined by analyzing nucleotide sequences (minimum of 180 bases) against the National Center for Biotechnology Information GenBank database (http://blast.ncbi.nlm.nih.gov). GenBank accession nos. JF290388–JF290395 and JF297995–JF298002.
