Treponema Pallidum Nucleic Acid

Syphilis is a common sexually transmitted disease in clinical practice, mainly referring to a chronic, systemic sexually transmitted disease caused by Treponema Pallidum (TP) infection. Syphilis is mainly spread through sexual transmission, mother-to-child transmission and blood transmission. Syphilis patients are the only source of infection, and Treponema pallidum can be present in their semen, breast milk, saliva and blood. Syphilis can be divided into three stages according to the course of the disease. The syphilis of primary stage may manifest as hard chancre and swollen inguinal lymph nodes, at this time the most infectious. The syphilis of secondary stage may manifest as syphilitic rash, the hard chancre subsides, and infectivity is also strong. The syphilis of tertiary stage may manifest as bone syphilis, neurosyphilis, etc.
