summary

I don't know if I've had too much sex recently. I feel that I've got venereal syphilis now, and I feel like vomiting as soon as I eat. Today, let me learn how to get syphilis with you.

How does syphilis get

The first aspect: Treponema pallidum from the epidermis or mucosal damage into the body, after 3-4 weeks of incubation period after the onset. The main symptoms of primary syphilis are chancre, ulcer in genital area and swelling of inguinal lymph nodes.

The second aspect: syphilis is caused by Treponema pallidum, which is a very complex microorganism and contains many antigen substances. Under electron microscope, the outermost layer of Treponema pallidum is the outer membrane, and the inner part of the outer membrane is the cytoplasmic membrane.

Third aspect: Treponema pallidum enters the human body from the intact mucous membrane and the abraded skin, invades the nearby lymph nodes after several hours, and spreads through the blood circulation on 2-3 days. In addition to sexual contact, there are blood borne transmission, placental transmission, birth canal transmission, indirect contact transmission and so on.

matters needing attention

The detection of IgM antibody to Treponema pallidum is a new method for the diagnosis of syphilis in recent years. IgM antibody is a kind of immunoglobulin, which has the advantages of high sensitivity, early diagnosis and determination of whether the fetus is infected with Treponema pallidum. The production of specific IgM antibody is the first humoral immune response after infection with syphilis and other bacteria or viruses. It is generally positive in the early stage of infection, and increases with the development of the disease, and then the IgG antibody rises slowly. After effective treatment, IgM antibody disappeared and IgG antibody persisted. TP IgM disappeared in 2-4 weeks after penicillin treatment in TP IgM positive primary syphilis patients. After penicillin treatment, the IgM disappeared in 2-8 months. In addition, the detection of TP IgM is of great significance for the diagnosis of congenital syphilis in newborns, because the IgM antibody molecule is large, and the maternal IgM antibody can not pass through the placenta. If TP IgM is positive, it means that the baby has been infected.
