BLSOMs for influenza virus genome sequences. (A) Di, Tri and Tetra. Di-, tri- and tetra-nucleotide BLSOMs have been constructed for 14,447 strains of influenza A and B virus. Lattice points containing sequences from strains isolated from more than one host are indicated in black, and those containing sequences from one host are indicated in a color: avian, red; human, green; swine, blue; equine, yellow; bat, gray; and influenza B, light blue; (B) Human subtype. On each BLSOM in A, individual human virus subtypes are specified in a color representing the subtype: H1N1, brown; H1N1/09, dark green; H2N2, gray; H3N2, blue; H5N1, red; H7N9, purple; other H7 and H9, pink; other human subtype, green; and territories of other hosts are achromatic; and (C) Avian subtype. On each BLSOM in A, individual avian virus subtypes are specified in a color representing the subtype: H5N1, gray; H7N2, light blue; H7N3, blue; H9N2, brown; other avian subtype, red; and territories of other hosts are achromatic.
