Syphilis is a sexually transmitted disease (STD) caused by a type of bacteria called Treponema pallidum. In its earliest stage, syphilis produces an open sore (ulcer) that leaks fluid filled with syphilis bacteria.
Syphilis is caused by a spirochete, Treponema pallidum. A spirochete is a thin spiralor coil-shaped bacterium that enters the body through the mucous membranes or breaks in the skin. In 90% of cases, the spirochete is transmitted by sexual contact.rimary syphilis is the stage of the organism's entry into the body. The first signs of infection are not always noticed. After an incubation period ranging between 10 and 90 days, the patient develops a chancre, which is a small blister-like sore about 0.5 in (13 mm) in size.
