FIG 3.

Summary of analyses to assess transition of influenza A viruses from a specific functional group of wild birds to the low-pathogenic H5 avian influenza A viruses detected in domestic poultry. In this figure, phylogeographical analyses showed one recent and representative H5 low-pathogenic introduction in North American poultry, CPF-MO-2016(H5N1), which is an introduction of virus in Missouri turkey as an example. The trees shown in the figure are constructed on the basis of the maximum clade credibility phylogenetic trees. Phylogeographical analyses were performed using all isolates for each inferred H5 introduction. Branches of the phylogenetic trees were colored according to the estimated ancestral state of the functional group of wild birds from discrete trait reconstruction. Arrow widths are based on the Bayes factor support levels. Statistical support is provided in greater detail in Table S3.
