STI Treponema pallidum

Venereal syphilis is caused by the bacterium Treponema pallidum.

It is an infection that is transmitted by contact between an uninfected person with an anogenital lesion and an infected person during intercourse. The infected mother can transmit to the fetus and cause a congenital infection.

Symptoms

Approximately 50% of patients will not develop symptoms and will only be diagnosed by laboratory tests. Venereal syphilis is a sexually transmitted infection that, without treatment, evolves in different stages that are characterized by the duration and location of the infection.

Early syphilis is characterized by the appearance of a single indurated and painless chancre with a clean base, defined and raised borders and an anogenital location (penis, vulva or cervix).

Detection

At Bioclinic Laboratories, the PCR test is performed from urine by highly trained personnel, with the highest quality standards. In addition, the VDRL test (anti-treponemal antibodies) is performed, a test for screening to rule out syphilis, since this bacterium can also be transmitted by being in contact with the blood of another infected person.
