A. Causative organism: treponema pallidum (spirochete).
B. Mode of infection:
1) Sexual route: sexual intercourse.
2) Non-sexual route: materno-fetal (placental).
C. Predisposing factors: multiple sexual partners.
Primary syphilis: (incubation period= 2- 6 weeks)
– Chancre: (the commonest site is cervix)
– Single, punched out & painless
– Heals spontaneously within 4 weeks.
– Inguinal lymphadenopathy.
Secondary syphilis: (incubation period= 2- 6 months after the primary)
– Generalized maculopapular skin rash.
– Mucous patches and condylomata lata.
– Generalized lymphadenopathy especially epitrochlear lymph nodes.
Tertiary syphilis: (incubation period= 2- 20 years)
– Cardiovascular lesions especially aortic regurge.
– Neurosyphilis: tabes dorsalis.
♦♦♦ Fluorescent treponemal antibody (FTA) test is the most sensitive & specific test for $.
♦♦♦ For obvious lesions: biopsy to detect syphilitic granulation tissue & EAO.
♦♦♦ For non-obvious lesions: (serological tests)
– Non-specific e.g. Wasserman reaction.
– Specific: e.g. TPI (treponema pallidum immobilization test).
A. Prevention: prevention of STD.
B. Active treatment:
– Benzathine penicillin: 2.4 million IU / week for 3 weeks.
– Side effects: Jarisch- Hexaheimer reaction.
C. Treatment during pregnancy:
– Penicillin: if the patient is sensitive, desensitization is done.
– Tetracycline & erythromycin aren’t used.

Syphilis|microbiology|-animated quick review video
Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum subspecies pallidum. The signs and symptoms of syphilis vary depending in which of the four stages it presents (primary, secondary, latent, and tertiary). The primary stage classically presents with a single chancre (a firm, painless, non-itchy skin ulceration) but there may be multiple sores. In secondary syphilis a diffuse rash occurs, which frequently involves the palms of the hands and soles of the feet. There may also be sores in the mouth or vagina. In latent syphilis, which can last for years, there are few or no symptoms. In tertiary syphilis there are gummas (soft non-cancerous growths), neurological, or heart symptoms. Syphilis has been known as “the great imitator” as it may cause symptoms similar to many other diseases.
