Noninvasive Surveillance and Evolutionary Insight into Siadenovirus among Antarctic Penguins

Figure 2

Maximum-likelihood phylogenetic tree analysis of hexon genes of siadenovirus. Strains in the tree are shown by name in bold for strains recently isolated from penguin species in Antarctica. Siadenovirus strains previously reported are shown by accession number followed by virus name. Numbers at the branches show bootstrap values. The bar at the bottom of the tree denotes distance.
