Treponema
''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. __TOC__ 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 Microaerophile, microaerophilic, Gram-negative bacteria, gram-negative, spirochaete bacterium with subspecies that cause the diseases syphilis, bejel (also known as endemic syphilis), and yaws. It is known to be transmitted only among humans and baboons. ''T. pallidum'' can enter the host through mucosal membranes or open lesions in the skin and is primarily spread through sexual contact. It is a helically coiled microorganism usually 6–15 μm long and 0.1–0.2 μm wide. ''T. pallidum'''s lack of both a Citric acid cycle, tricarboxylic acid cycle and processes for oxidative phosphorylation results in minimal metabolic activity. As a Chemoorganoheterotrophic, chemoorganoheterotroph, ''Treponema pallidum'' is an obligate parasite that acquires its glucose carbon source from its host. Glucose can be used not only as a primary carbon source but also in glycolytic mechanisms to generate ATP needed to power the ...
