Clos·trid·i·um per·frin·'gens

a bacterial species that is the chief causative agent of gas gangrene in humans and a cause of gas gangrene in other animals, especially sheep; it may also be involved in causing enteritis, appendicitis, and puerperal fever; it is one of the most common causes of food poisoning in the U. S. This organism is found in soil, water, milk, dust, sewage, and the intestinal tract of humans and other animals.

Clostridium perfringens

A bacterium that can cause gas gangrene and food poisoning in humans and various diseases in livestock.

Clostridium perfringens

Etymology: Gk, kloster, spindle
a species of anaerobic gram-positive bacteria capable of causing gas gangrene and food poisoning in humans and various digestive and urinary tract diseases in livestock. The oval spores of the bacteria are found in the soil and in the intestinal tracts of humans and animals. It is the third most common form of food poisoning in the United States and the United Kingdom. Incubation time is 6 to 24 hours, usually 10-12 hours. Symptoms include abdominal cramps and diarrhea. Vomiting is rare. Also called Clostridium welchii.
