Toxicity Profile
Route of ExposureIngestion (4) ; inhalation (4) ; dermal (4)
Mechanism of ToxicityPerfringolysin O binds to cholesterol on eukaryotic cell membranes, then forms oligomeric pores. This causes membrane damage and lysis of the cell. (1)
MetabolismFree toxin may be removed by opsonization via the reticuloendothelial system (primarily the liver and kidneys) or it may be degraded through cellular internalization via the lysosomes. Lysosomes are membrane-enclosed organelles that contain an array of digestive enzymes, including several proteases.
Toxicity ValuesLD50: 13-16 ug/mg (Intravenous, Mouse) (2)
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesPerfringolysin O (PFO) is produced by Clostridium perfringens. (1)
Minimum Risk LevelNot Available
Health EffectsPerfringolysin O (PFO) is produced by Clostridium perfringens. Clostridium perfringens can cause infections producing tissue necrosis and clostridial myonecrosis. Ingestion causes food poisoning. (1, 3)
SymptomsIngestion of Clostridium perfringens causes food poisoning characterized by colic, diarrhoea and sometimes nausea. Infections show evidence of tissue necrosis, bacteremia, emphysematous cholecystitis, and gas gangrene, which is also known as clostridial myonecrosis. (3)
TreatmentClostridium perfringens infections can be treated with antibiotics. (3)
