Microbiology

  • Gram-positive bacillus
  • Member of the genus Clostridium

Clinical Presentation

  • Can cause bacteremia and non-traumatic myonecrosis
  • Clinical presentation is typically fulminant sepsis, which very high mortality

Management

  • Aggressive surgical debridement, possibly including amputation
  • Broad-spectrum antibiotics for necrotizing fasciitis are indicated until the microbiologic diagnosis is confirmed
  • First-line antimicrobials are penicillin 2-4 million units IV q4h plus clindamycin 600-900 mg IV q6h
