Treponema pallidum is an obligate parasite bacteria, meaning they can't survive outside a living body. However, for individuals that acquire syphilis by physically touching a lesion or in some other way, the primary chancre might appear on the hands or some other part of the body. “Complete genome sequence of Treponema pallidum, the syphilis spirochete.” Science.

Treponema pallidum can be considered a gram-negative bacterium although its cell envelope differs from other gram-negative bacteria. This strategy is rapid and inexpensive and able to detect acute syphilis, but false-negative results are possible, especially in early and late syphilis. Syphilitic chancres typically heal on their own over a few months, but during that time, some spirochetes go to nearby lymph nodes where they cause lymphadenopathy, which is lymph node enlargement, and then they get into the lymph and finally into the bloodstream. link:(11) Sheila A. Lukehart, Ph.D., Charmie Godornes, B.S., Barbara J. Molini, M.S., Patricia Sonnett, B.S., Susan Hopkins, M.D., Fiona Mulcahy, M.D., Joseph Engelman, M.D., Samuel J. Mitchell, M.D., Ph.D., Anne M.

The first stage is called primary syphilis or the early localized stage, and it usually starts 1 to 3 weeks after the T. pallidum lands on the skin or mucous membrane.
