Anaerobic bacteria grow in places which completely, or almost completely, lack oxygen.
They are normally found in the mouth, gastrointestinal tract, and vagina, and on the skin. Commonly known diseases caused by anaerobic bacteria include gas gangrene, tetanus, and botulism. Nearly all dental infections are caused by anaerobic bacteria. Usually, the immune system kills any invading bacteria, but sometimes the bacteria are able to grow and cause an infection.
