Orthopoxvirus DNA in Eurasian Lynx, Sweden
Figure 3

Figure 3. Phylogenetic tree (neighbor-joining method) generated from alignment of identical partial orthopoxvirus (OPV) thymidine kinase (tk) gene sequences obtained from 21 Eurasian lynx (Lynx lynx) from Sweden (designated OPV-TK-23) and corresponding sequences from cowpox virus isolates and other members of the genus Orthopoxvirus as well as other genera of the family Poxviridae. The corresponding tk gene sequences of 2 fowlpox viruses (genus Avipoxvirus) were used to root the tree. Only bootstrap values >60 are shown. Scale bar represents distances in substitutions per site.
