Final answer:
All the listed sexually transmitted diseases except for herpes can be treated with antibiotics. Herpes, caused by a virus, requires antiviral medications.
Step-by-step explanation:
The sexually transmitted diseases (STDs) that can be treated with antibiotics are chlamydia, gonorrhea, and syphilis. These are caused by bacteria and can usually be cured with antibiotics. However, herpes is a sexually transmitted disease caused by a virus, and therefore, cannot be cured with antibiotics. Instead, herpes is managed with antiviral medications which help to control outbreaks and symptoms but do not eliminate the virus from the body.
