A Genotypic diversity of 58 A(H5N1) viruses (some sequences generated directly from clinical material). A list of viruses used in this study and their GenBank or GISAID accession numbers are provided in Supplementary Tables 3 and 4, respectively. The colors denote common genotypes, with the orange color representing genes of Eurasian lineage and blue representing genes of NAm lineage (the different shades of blue represent phylogenetically distinct NAm genes). B Representative tangle plot showing the association of A(H5N1) virus HA genes (left side) with PB2 genes (right side) of Eurasian and NAm lineages. Nodes on the PB2 tree represent A(H5N1) viruses and representatives of other subtypes. Asterisks (*) indicate viruses that were used in subsequent experiments.
