Figure. Phylogenetic trees of hemagglutinin (A) and neuraminidase (B) genes of H5 and N6 subtype influenza viruses collected from poultry and humans in China, 2021, and reference viruses. Red triangles indicate virus obtained in this study; red circles indicate human-infected avian influenza viruses; green squares indicate H5 Re-11 vaccine strain. Clade numbers and lineages are indicated on the right in panel. Trees were constructed with MEGA 5.10 software (https://www.megasoftware.net) using the neighbor-joining method. Bootstrap analysis was performed with 1,000 replications. Scale bars indicate nucleotide substitutions per site.
