There are antibiotics to cure bacterial STDs, like chlamydia, syphilis, and gonorrhea, and to cure parasitic or protozoal STDs, like pubic lice and trichomoniasis. Antibiotics don't cure viral STDs like hepatitis B and C, herpes, HIV, and genital warts. Yes; the antibiotic will remove the bacteria. Antibiotics will cure the bacterial and protozoa STDs. It will kill the bacteria from such STIs as chlamydia, gonorrhea, and syphilis.
Some diseases are caused by organisms that can be killed by antibiotics, such as certain bacteria. Some are caused by organisms that are not affected by antibiotics, such as viruses. Other illnesses may be caused by diet (such as scurvy) or an inherited defect (such as Huntington's Disease, or Sickle cell Anemia)- and antibiotics have no effect on those things.
Antibiotics will kill bacteria, or render them incapable of reproducing; a wide variety is available and can be tailored to most types of bacteria. There are treatments for some viral infections (acyclovir, gancyclovir and AZT are some better-known examples), but they are less effective than antibacterial drugs and are not used for minor illnesses such as the common cold.
