Nearly all dental infections are caused by anaerobic bacteria. Sexually transmitted diseases (STDs) like syphilis, gonorrhea and chlamydia are also caused by anaerobic bacteria. Anaerobic bacteria can cause an infection when a normal barrier (such as skin, gums, or intestinal wall) is damaged due to injury, surgery, or disease. Usually, the immune system kills any invading bacteria, but sometimes the bacteria are able to grow and cause an infection. Body sites that have tissue destruction (necrosis) or a poor blood supply are low in oxygen and favor the growth of anaerobic bacteria. Risk Factors: People who have experienced shock, injury, or surgery, and those with blood vessel disease or tumors are at an increased risk for infection by anaerobic bacteria. Symptoms: Common Symptoms: Fever with or without chills ...
