Overview
The causative organisms vary depending on the type of necrotizing fasciitis. Type I (polymicrobial), Type II (monomicrobial), Type III (gram negative monomicrobial including marine related organisms) and Type IV (fungal).
Causes
Necrotizing fasciitis may be caused by the following organisms:[1]
| Type | Organism |
|---|---|
| Type 1 (70%-80% cases) Polymicrobial/Synergistic[2][3][4] |
● Mixed aerobes, anaerobes and facultative anerobic bacteria ● Often bowel flora-derived ● Affects immunocomprmised or those with underlying abominal pathology |
| Type 2 (20% to 30% cases) Monomicrobial |
● Beta-Hemolytic Streptococci group A (Streptococcus pyogenes) ● with/without Staphylococcus aureus ● Skin or throat derived |
| Type 3 (common in Asia) Gram negative monomicrobial NF (including marine related organisms) |
● Vibrio spp mainly ● Raw oyster ingestion (V.Vulnficus) ● Wound contamination with sea water ● Non-vibrio spp (Pasteurella multocida, Haemophilus influenzae, Klebsiella spp and Aeromonas spp) |
| Type 4 (Fungal) | ● Candida (Immunocompromised patients) ● Zygomycetes such as Mucor and Rhizopus spp (Immunocompetent patients) |
