Background
Microbiology
- Often encapsulated short Gram-variable bacilli of varying length
- Found in soil and humans and animals intestines
- Makes necrotizing extracellular toxins
- Four types:
- Type A: foodborne outbreaks associated with poorly heated food and meat; gas gangrene in patients with necrotic bowel
- Type C: pork product ingestion followed by enteritis necroticans (hemorrhagic necrosis of the jejunum)
- Type B & D: no disease in humans
Management
- For gas gangrene, typically requires surgical debridement and penicillin G
- Consider adding clindamycin for theoretical decreased toxin production in toxic shock syndrome
- Otherwise, generally susceptible to erythromycin, chloramphenicol, cefazolin, cefoxitin, ceftriaxone, piperacillin, carbapenems, metronidazole, vancomycin, and linezolid
