 Treponema pedis
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).
