On the Origin of the Treponematoses: A Phylogenetic Approach
Figure 3
A phylogenetic tree depicting the relationships between theT. pallidum subspecies.
This maximum likelihood tree is based on 20 polymorphic regions in theT. pallidum genome. Bootstrap support was estimated with 1,000 replicates in order to assess confidence at branching points and are shown within circles where values are high (>90%). Bootstrap support values for both maximum likelihood and maximum parsimony trees are shown, in that order.
