Taxonomy/phylogeny:
 
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. T. paraluiscuniculi is very closely related to T. pallidum subsp. pallidum and T. pallidum subsp. pertenue. See the phylogenetic tree (Fig. 134:1). Some researchers regard the two latter as separate species.
Comment:Has not been cultivated in vitro. The disease cannot be transmitted to humans.
Reference(s): No. 54, 55
