|syphilis (sĭf'ə-lĭs) Pronunciation Key
A sexually transmitted disease caused by the spirochete Treponema pallidum that is characterized in its primary stage by genital sores. If untreated, skin ulcers develop in the next stage, called secondary syphilis. As the disease progresses to potentially fatal tertiary syphilis, neurologic involvement with weakness and skeletal or cardiovascular damage can occur.
A sexually transmitted disease caused by a microorganism. In its initial stages (called primary syphilis), it is manifested by a skin ulcer called a chancre. If the disease is not treated by penicillin or other antibiotics, the infection becomes chronic. In so-called tertiary syphilis, virtually any tissue in the body can be damaged, including the cardiovascular and nervous systems. The disease, if left untreated, can cause blindness, mental illness, and death.
