|About 25 different species have been described within the genus Treponema. There are different opinions among researchers about which should be regarded as separate species or only as subspecies of a certain species. Some researchers think that e.g. T. pallidum subsp. pallidum and T. pallidum subsp. pertenue should be regarded as different species, although they are very closely related from a phylogenetic point of view. See the phylogenetic tree (Fig. 188:3).
