Figure 4. Phylogenetic analysis based on the tpr genes and SNVs of T. pallidum.

. A. Phylogenetic tree showing clusters of Subfamily I of tpr genes. B. Phylogenetic tree showing clusters of Subfamily II of tpr genes. C. Phylogenetic tree showing clusters of tpr genes based on genomic SNVs after the removal of SNVs from the tprD and tprG genes. The tree was constructed using MrBayes 3.1. Significant linkages using Bayesian phylogenetic inference analysis were considered as probabilities of 100%.
