Flesh eating bacteria refers to a condition called necrotizing fasciitis. Though rare, this condition has become popular through media reports in recent times. In this serious condition, the bacterium that is involved destroys the skin, fat and tissue which cover the muscles in a short span of time. The organism spreads aggressively once it enters the body. Necrotizing fasciitis is caused by one or more than one type of bacteria. However, the term flesh eating bacteria is generally referred to a bacterium called streptococcus pyogenes. This serious infection generally affects abdomen, arms and legs.At least 500 to 600 people in United States are affected by flesh eating bacteria. The rate of fatality is more than 25 to 30%. The condition is rare in children.
What Are the Causes of Necrotizing Fasciitis?
The term flesh eating bacteria is so used because the toxin produced by the bacteria rapidly destroys the body tissues. Most often the organism involved is streptococcus pyogenes. It is a member of group A streptococci. It is the same bacterium that is responsible for sore throat, scarlet fever, streptococcal skin infection etc. In rare instances, other bacteria are also involved.The source of infection is skin, through minor or major trauma. It can also be bowels after abdominal surgery. In this case the infection is polymicrobial. It may be associated with anerobic organisms.

- Administration of intravenous antibiotics.
- Surgical removal of dead and necrosed tissue.
- Raising the blood pressure.
