Final answer:
Latent syphilis can be diagnosed through blood tests, including serological testing and examination of lesion tissue. The recommended treatment for syphilis is parenteral penicillin G.
Step-by-step explanation:
Latent syphilis is a stage of the disease where there are no symptoms, but the bacteria still remain in the body. Blood tests are used to detect the disease during this stage. The recommended treatment for syphilis is parenteral penicillin G, although other antibiotics can be used for those who are allergic to penicillin.
Tests for diagnosing latent syphilis include darkfield or brightfield silver stain examination of lesion tissue or exudate, as well as serological testing such as VDRL-CSF for neurosyphilis and prenatal TORCH panel. To diagnose neurosyphilis, a variety of factors including reactive serologic test results and cerebrospinal fluid abnormalities are assessed. Screening for syphilis is recommended for all pregnant women to prevent transmission to the fetus.
