Treponema Faecavium
''Treponema'' is a genus of spiral-shaped bacteria. The major treponeme species of human pathogens is ''Treponema pallidum'', whose subspecies are responsible for diseases such as syphilis, bejel, and yaws. ''Treponema carateum'' is the cause of pinta. ''Treponema paraluiscuniculi'' is associated with syphilis in rabbits. ''Treponema succinifaciens'' has been found in the gut microbiome of traditional rural human populations. Phylogeny The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI).

Treponema Pallidum
''Treponema pallidum'', formerly known as ''Spirochaeta pallida'', is a spirochaete bacterium with various subspecies that cause the diseases syphilis, bejel (also known as endemic syphilis), and yaws. It is transmitted only among humans. It is a helically coiled microorganism usually 6–15 μm long and 0.1–0.2 μm wide. ''T. pallidum'''s lack of either a tricarboxylic acid cycle or oxidative phosphorylation results in minimal metabolic activity. The treponemes have a cytoplasmic and an outer membrane. Using light microscopy, treponemes are visible only by using dark field illumination. ''Treponema pallidum'' consists of three subspecies, ''T. p. pallidum, T. p. endemicum,'' and ''T. p. pertenue,'' each of which has a distinct associated disease. Subspecies Three subspecies of ''T. pallidum'' are known: * ''Treponema pallidum pallidum'', which causes syphilis * ''T. p. endemicum'', which causes bejel or endemic syphilis * ''T. p. pertenue'', which causes yaw ...
