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.
