Treponema pallidum (Spirochete) is the causative agent of syphilis. In the past, localization of the spirochete agent was achieved with silver stains such as Steiner’s and/or Warthin-Starry. Treponema pallidum can now be successfully localized with immunohistochemical techniques in formalin-fixed paraffin-embedded tissue. Studies

Epidemiology. Syphilis is caused by a spirochete organism, Treponema Pallidum, which has a thin, slow-moving, corkscrew-like body. Other variants of this family of Treponematoses include Treponema pertenue (yaws), Treponema endemicum (bejel), and Treponema carateum (pinta). Venereal syphilis is thought to have mutated.

Syphilis is a sexually transmitted disease (STD) caused by the bacterium Treponema pallidum. Syphilis is passed from person to person through direct contact with a syphilitic chancre. Chancres occur mainly on the external genitals, vagina, anus, or in the rectum but can also occur on the lips and in the mouth.
