which of the following is an agent of a sexually transmitted disease?
Answer Details
Treponema pallidum is an agent of a sexually transmitted disease.
Sexually transmitted diseases (STDs) are infections that are spread through sexual contact. Treponema pallidum is a bacterium that causes syphilis, a type of STD. Syphilis is typically transmitted through direct contact with a syphilis sore during sexual activity.
The other options you listed are not sexually transmitted diseases:
