Infectious diseases

Antibiotics are medications that destroy bacteria or slow down their growth.  You might wonder about why your medical provider prescribes antibiotics for some conditions, but not for others. 

When you might be prescribed antibiotics

If you are diagnosed with a bacterial infection, your provider may write you a prescription for antibiotics.  Bacteria are microscopic organisms that can sometimes cause the following infections:

Staphylococcus aureus (or S. aureus) also called staph, are bacteria commonly found on human skin; common places include inside the nose, in the armpit, groin, and genital area.

When bacteria are found on the skin but do not cause illness it is called "colonization." When the bacteria do cause illness the person is said to be "infected" with staph.


TB, or tuberculosis, is a disease caused by a bacteria named M. tuberculosis. This bacteria can infect any part of the body, but it most commonly affects the lungs. TB is spread through the air from one infected person to another.

There are two types, or stages, of TB. The first is latent, or inactive, TB. In latent TB, there are live TB bacteria inside a person, but that person is not sick. Someone with latent TB feels fine: no cough, no fever. Someone with latent TB cannot spread this infection.
