Clostridium perfringens

Clostridium perfringens is a spore-forming, anaerobic bacterium found in soil and animal intestines. It causes foodborne illness and can cause gas gangrene.

Clostridium perfringens enterotoxin: A pore-forming toxin that disrupts intestinal cells and causes diarrhea and abdominal cramps. It is released when toxin-producing cells sporulate in the intestine during food poisoning.
Clostridium perfringens food poisoning: A foodborne illness marked by abdominal cramps and diarrhea, typically beginning hours after contaminated food is eaten. This is the common intestinal disease caused by the bacterium.
Clostridium: A genus of anaerobic, spore-forming bacteria that includes species causing disease and species found in soil or intestines. C. perfringens belongs to this diverse group of spore-forming bacteria.
Clostridium botulinum: A spore-forming anaerobic bacterium that produces botulinum neurotoxins and causes botulism. Both are spore-forming clostridia, but their defining toxins and disease patterns differ.
Alpha toxin: A phospholipase toxin that damages cell membranes and contributes to tissue destruction and hemolysis. Its membrane-damaging activity helps drive the tissue injury of gas gangrene.
Food safety: The practices and systems used to prevent food contamination and foodborne illness. Prompt cooling and safe holding temperatures limit bacterial growth in cooked foods.
Gram-positive bacteria: Bacteria that retain crystal violet stain because their cell envelopes contain a thick peptidoglycan layer. C. perfringens has the Gram-positive cell-envelope structure used in its classification.
Clostridium tetani: A spore-forming bacterium that produces tetanus neurotoxin, causing painful muscle spasms. It shares the genus and anaerobic growth, but causes neurotoxicity rather than typical C. perfringens syndromes.
Gas gangrene: A rapidly progressive infection of muscle and other tissues, often involving gas production and tissue necrosis. C. perfringens is a major cause, using toxins and fermentation in damaged tissue.
Clostridium perfringens diagnosis: Laboratory identification of C. perfringens or its toxins in clinical, food, or environmental samples. Diagnosis distinguishes foodborne outbreaks and wound infections from similar illnesses.
