Partial gene sequences are indicated with a “*” symbol after the strain name. The gene sequences of A/swine/Togo/ONA32/2013(H1N1) (in large bold font) were compared to all West and Central African human (H1N1)pdm09 sequences available on GenBank, as well as to the closest blast hit for which a full genome was available (A/Texas/JMM_52/2012[H1N1], whose gene segments shared consistently <99.4% identity with A/swine/Togo/ONA32/2013(H1N1) gene segments), to a 2013 representative virus, A/Helsinki/819/2013, and to the recommended vaccine strain (A/California/4/2009[H1N1]) (in bold italic font). Swine viruses are underlined. The number of bootstrap replications was set to 500, and bootstrap values above 50 are labeled on major tree branches for reference. Phylogenetic trees of the A) hemagglutinin (HA); B) polymerase basic 2 (PB2); C) polymerase basic 1 (PB1); D) polymerase acidic (PA); E) nucleoprotein (NP); F) neuraminidase (NA); G) matrix (M); and H) non-structural protein (NS) gene segments are shown.
