What is syphilis?
What is syphilis?
Syphilis is a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum. This bacterium is tricky – it can't be grown in the lab.
What are the symptoms of primary syphilis?
What are the symptoms of primary syphilis?
Syphilis progresses through stages. The first stage features a painless sore on the genitals, often appearing as a single ulcer called a chancre. Swollen lymph nodes may also be present.
What are the symptoms of secondary syphilis?
What are the symptoms of secondary syphilis?
The second stage of syphilis is marked by a rash that can appear anywhere on the body, including the palms of the hands and soles of the feet. Other symptoms may include fever, hair loss, and sore throat.

Study Notes
Laboratory Diagnosis of SYPHILIS - Treponema Pallidum
- Syphilis is caused by the bacterium Treponema pallidum, which cannot be grown in artificial media.
- Syphilis is primarily transmitted through sexual contact.
- The first stage of syphilis presents as a painless sore on the genitals and swollen lymph nodes.
- The second stage of syphilis presents as a rash, which can be diagnosed through skin lesions and palmoplantar involvement.
- Spirochetes are present in the primary and secondary stages of syphilis.
- The third stage of syphilis can remain dormant for years and can lead to severe complications such as blindness, paralysis, and cardiovascular diseases.
- Syphilis can be transmitted vertically during any stage of gestation or clinical stage of the disease, leading to congenital syphilis in newborns.
- Congenital syphilis can be prevented by treating the infection before the 16th week of gestation.
- 50% of infected newborns are asymptomatic at birth, with symptoms appearing at 3 months of age.
- Early onset congenital syphilis presents with similar symptoms to secondary syphilis, including mucous patches and condyloma latum.
- Late onset congenital syphilis can lead to neurological and skeletal complications.
- Laboratory diagnosis of syphilis includes microscopy in dark field and serology testing using non-treponemal and treponemal antigens, such as VDRL and TPHA.
