Syphilis antibodies turned negative.

Syphilis is a sexually transmitted disease caused by Treponema pallidum infection. Patients infected with syphilis can be treated with penicillin in an early stage and can be cured. There are two kinds of syphilis antibodies, one is specific antibody and the other is non-specific antibody. Non-specific antibody negative indicates that the patient has recovered, and specific antibody can be positive for life.
