FIG 1.

Phylogenetic analysis of seal influenza A(H10N7) virus HA amino acid sequences. (A) Schematic overview of the locations where seals were found; samples were collected from these seals to determine the complete HA sequence. Samples were numbered according to the date found. Colors indicate the areas where the seals were found (orange, Kattegat, Sweden, and Denmark; yellow, Skagerrak, Sweden; green, Schleswig-Holstein, Germany; light blue, Limfjorden, Denmark; pink, North Sea coast, Denmark; blue, Niedersachsen, Germany; purple, Vlieland, the Netherlands; and magenta, Zeeland, the Netherlands). (B) Median joining network of seal influenza A(H10N7) viruses and a closely related avian influenza virus strain (A/Mallard/1/2014). Amino acid changes are indicated at each network branch, and sample numbers are indicated at each position in the network. (C) Bayesian analysis of complete seal influenza A(H10N7) virus HA gene nucleotide sequences. A closely related avian influenza virus strain (A/Mallard/1/2014) was used as an outgroup. Posterior values are indicated at nodes.
