Unrooted trees constructed from whole genome sequences of syphilis strains. Trees were constructed using the Neighbour-Joining method using the Tamura-Nei genetic distance model and 1000 bootstrap replicates. The numbers above the branches show bootstrap support and the bar scale represents 0.0001 substitutions per target site. (a) A tree constructed from the alignment of genomes from strains Chicago (CP001752.1), DAL-1 (CP003115.1) and Mexico A (CP003064.1) with original versions of whole genome sequences of TPA Nichols (AE000520.1) and SS14 (CP000805.1). (b) A tree constructed from the alignment of genomes from strains Chicago (CP001752.1), DAL-1 (CP003115.1) and Mexico A (CP003064.1) with the improved whole genome sequences of Nichols-RS (CP004010.2) and SS14-RS (CP004011.1).
