Treponema

 [trep″o-ne´mah]
a genus of gram-negative, motile bacteria, spirochetes found in the oral, intestinal, and genital mucosa. Pathogenic species include T. cara´teum, the etiologic agent of pinta; T. pal´lidum subsp. pal´lidum, the etiologic agent of syphilis; and T. pal´lidum subsp. perte´nue, the etiologic agent of yaws.
Treponema pallidum complement fixation test (Treponema pallidum hemagglutinin test) (Treponema pallidum immobilization test) formerly common serological tests for the diagnosis of syphilis, related directly to the causative organism.

treponema

 [trep″o-ne´mah]
an organism of the genus Treponema. adj., adj trepone´mal.

Treponema

(trep'ō-nē'mă),
A genus of anaerobic bacteria (order Spirochaetales) consisting of cells, 3-8 mcm 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 Treponema pallidum.
[G. trepō, to turn, + nēma, thread]

(trĕp′ə-nē′mə)
n. pl. trepone·mata (-mə-tə) or trepone·mas
Any of a group of spirochetes of the genus Treponema, including those that cause syphilis, pinta, and yaws.

Trep·o·ne·ma

(trepō-nēmă)
A genus of anaerobic bacteria (order Spirochaetales) consisting of cells, 3-8 mcm in length, with acute, regular, or irregular spirals and no obvious protoplasmic structure. They stain with difficulty except with silver impregnation stain, with which they are visible using a dark field microscope. Some species are pathogenic and parasitic for humans and other animals, generally producing local lesions in tissues.
