syphilis -
a common venereal disease caused by the treponema pallidum spirochete; symptoms change through progressive stages; can be congenital (transmitted through the placenta)
Syphilis is a sexually transmitted disease caused by the spirochetal bacterium Treponema pallidum subspecies pallidum. The route of transmission of syphilis is almost always through sexual contact, although there are examples of congenital syphilis via transmission from mother to child in utero or at birth. The signs and symptoms of syphilis are numerous; before the advent of serological testing, precise diagnosis was very difficult.

syphilis A sexually transmitted disease (STD) caused by the bacterium Treponema pallidum. In the early stage of syphilis, a genital or mouth sore called a chancre develops, but eventually disappears on its own. However, if the disease is not treated, the infection can progress over years to affect the heart and central nervous system. Syphilis can also be transmitted from an infected mother to her fetus during pregnancy, with serious health consequences for the infant.
