Final answer:
To confirm successful treatment of syphilis, blood tests, microscopy, and serologic tests can be used. Treatment usually involves penicillin or other antibiotics.
Step-by-step explanation:
The successful treatment of syphilis can be confirmed through various methods. One way is by conducting blood tests that detect specific antibodies for the syphilis bacterium. Another method is darkfield or brightfield microscopy of tissue or exudate from lesions to detect the bacteria. Additionally, serologic tests can be used for a presumptive diagnosis. These tests include the Venereal Disease Research Laboratory (VDRL) and rapid plasma reagin (RPR) tests. Confirmatory treponemal serologic tests are also performed. Treatment typically involves the use of penicillin or other antibiotics.
