The Treponema vincentii LA-1 (ATCC 35580) and Treponema

The Treponema vincentii LA-1 (ATCC 35580) and Treponema pallidum subsp. pallidum SS14 reference strains were selected as outgroups, using complete genomes obtained from GenBank under Accession numbers NZ_ACYH00000000 and NC_010741, respectively.
