Brief Answer:
Mode of transmission of syphilis

Detailed Answer:
Hi,

Thank you for your query. I can understand your concerns.
T. pallidum causative organism of syphilis can penetrate intact mucous membranes or microscopic abrasions in skin .
It is thus transmissible by kissing near a lesion, as well as oral (sucking genitals having lesion), vaginal, and anal sex.
Nearly all cases of syphilis are acquired by sexual contact with infectious lesions [i.e., the chancre, mucous patch, skin rash, or condylomata XXXXXXX ).
Less common modes of transmission include nonsexual personal contact, infection in utero, blood transfusion, and organ transplantation.
Hence anal sex is not the only mode of transmission of syphilis .

Brief Answer:
T. pallidum hemagglutination (TPHA) test & stages of syphilis

Detailed Answer:
Hi,

Thank you for your query. I can understand your concerns.
The T. pallidum hemagglutination (TPHA) test has a very high positive predictive value for diagnosis of syphilis.However this treponemal serologic test may give false-positive results at rates as high as 1–2%.
Hence this test is read in conjuction with The fluorescent treponemal antibody absorption (FTA-ABS) .
Since there is possibility of Biological false-positive tests for syphilis,interpretation requires historical and clinical evaluation and if serological tests are negative but there is clinical suspicion of syphilis retest in one month.
Stages of syphilis:-
Primary syphilis:
Both nontreponemal (VDRL/Venereal Disease Research Laboratory & RPR/the rapid plasma reagin ) and treponemal tests (TPHA) may be nonreactive in early primary syphilis, although treponemal tests are slightly more sensitive (85–90%) during this stage than nontreponemal tests (80%).
The fluorescent treponemal antibody–absorbed (FTA-ABS) test are more sensitive for primary syphilis .
Secondary syphilis:
All tests (VDRL ,RPR & TPHA,FTA-ABS)are reactive during secondary syphilis.
Late syphilis (tertiary syphilis):
VDRL and RPR sensitivity and titers may decline in untreated persons with late latent or late syphilis, but treponemal tests such as TPHA remain sensitive in these stages.
The VDRL test remains the standard for examining CSF for Neurosyphilis (Traditionally, neurosyphilis has been considered a late manifestation of syphilis).
