Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Yamuna Kondapally, M.B.B.S[2]

Overview

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).[1]

Causes

Causes

Necrotizing fasciitis may be caused by the following organisms:[2]

Type Organism
Type 1 (70%-80% cases)
Polymicrobial/Synergistic[3][4][5]
● 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[6][7]
● Beta-Hemolytic Streptococci group A (Streptococcus pyogenes)
● With/without Staphylococcus aureus
● Skin or throat derived
Type 3 (common in Asia)
Gram negative monomicrobial (including marine related organisms)[8][9]
● Vibrio spp mainly
● Raw oyster ingestion (Vibrio vulnificus)
● Wound contamination with sea water
● Non-vibrio spp (Pasteurella multocida, Haemophilus influenzae, Klebsiella spp. and Aeromonas spp)
Type 4 (Fungal)[1] ● Candida (Immunocompromised patients)
● Zygomycetes such as Mucor and Rhizopus spp (Immunocompetent patients)
