Which statement about the descriptor flesh-eating bacteria is true for Streptococcus pyogenes?

• A. It refers to a different genus.
• B. It is a virus.
• C. It is a fungus.
• D. It is commonly used to describe Streptococcus pyogenes.

Answer: (D)

“Flesh-eating bacteria” is a colloquial way to describe organisms capable of causing rapid soft-tissue destruction, and Streptococcus pyogenes is the classic example associated with this severe presentation. This organism, a Group A Streptococcus, can trigger necrotizing fasciitis, where toxins and tissue-destroying enzymes (like streptolysins, hyaluronidase, streptokinase, and DNases) promote fast, extensive damage to fascia and overlying tissues and can lead to systemic illness. Because of this strong association with necrotizing infections, the descriptor is commonly used for Streptococcus pyogenes. It is not a virus or a fungus, and it does not refer to a different genus. While other pathogens can cause aggressive soft-tissue infections, the term most closely and frequently points to Streptococcus pyogenes and its potential for necrotizing fasciitis.
