Necrotizing soft tissue infection is a rare but very severe type of bacterial infection. It can destroy the muscles, skin, and underlying tissue. The word "necrotizing" refers to something that causes body tissue to die.
Many different types of bacteria can cause this infection. A very severe and usually deadly form of necrotizing soft tissue infection is due to Streptococcus pyogenes, which is sometimes called "flesh-eating bacteria."
Necrotizing soft tissue infection develops when the bacteria enters the body, usually through a minor cut or scrape.
