Treponema

A genus of anaerobic bacteria (order Spirochaetales) consisting of cells, 3–8 μm in length, with acute, regular, or irregular spirals and no obvious protoplasmic structure. A terminal filament may be present. They stain with difficulty except with Giemsa stain or silver impregnation. Some species are pathogenic and parasitic for humans and other animals, generally producing local lesions in tissues. The type species is T. pallidum. [G. trepo, to turn, + nema, thread]
- T. carateum a bacterial species that causes pinta, or carate.
- T. cuniculi a bacterial species that causes spirochetosis in rabbits.
- T. denticola cultivatable bacterial species that does not ferment carbohydrates and can be isolated from the oral cavity of humans.
- T. genitalis a nonpathogenic bacterial species found on the genitalia of humans.
- T. hyodysenteriae an enteropathogenic bacterial species that causes swine dysentery.
- T. mucosum a bacterial species found in pyorrhea alveolaris; it possesses pyogenic properties.
- T. pallidum a bacterial species that causes syphilis in humans; this organism can be experimentally transmitted to anthropoid apes and to rabbits; it is the type species of the genus T..
- T. pertenue a bacterial species that causes yaws; patients with this disease give positive results in serologic screening tests for syphilis.

Trep·o·ne·ma (trep″o-neґmə) [trepo- + Gr. nēma thread] a genus of gram-negative bacteria of the family Spirochaetaceae, consisting of microaerophilic, spiral microorganisms that exhibit motility with a flexing, bending, snapping motion and divide by transverse fission. The outer surfaces have polar flagella that wind around the organism. They are found in the oral, intestinal, and genital mucosa. Pathogenic species, which cause syphilis, yaws, and pinta, have not been cultured in vitro.
