C. perfringens is also known to cause other diseases, such as infections of the skin and deeper tissues. This is known as “clostridial myonecrosis” or “gas gangrene” and also results from toxins produced by C. perfringens.
What are the Mode S of transmission for C perfringens?
MODE OF TRANSMISSION: Food Poisoning: Food-borne illness acquired by ingestion of large number of C. perfringens vegetative cells present in the food. Food sources are usually cooked meat, vegetables, fish or poultry dishes which have been stored at ambient temperatures for a long time after cooking.
What antibiotics treat Clostridium perfringens?
Penicillin G remains the drug of first choice for infections with C. perfringens; it need not be added to a regimen containing a penicillinase-resistant penicillin given parenterally in high doses. The cephalosporins should be considered as alternative drugs for penicillin-allergic patients.

What kills Clostridium perfringens?
The Organism: Clostridium perfringens are anaerobic bacteria that can produce spores. The bacteria can exist as a vegetative cell or in the dormant spore form in food. Thorough cooking (140°F) will kill the vegetative cells, but spores may survive.
What is unique about Clostridium perfringens?
Clostridium perfringens is a Gram-positive, anaerobic, rod-shaped bacterium from the Clostridium genus. It is both heat-resistant and cold-tolerant, surviving in conditions with little or no oxygen.
What color is Clostridium perfringens?
perfringens is a short, thick, Gram-positive bacillus. If there is evidence of contamination, streak contaminated culture(s) on TSC agar containing egg yolk and incubate in anaerobic jar 24 h at 35°C. Surface colonies of C. perfringens are yellowish gray with 2-4 mm opaque zones caused by lecithinase activity.
Is perfringens C contagious?
There are two specific types of clostridium in dogs, clostridium perfringens and clostridium difficile. Both types of clostridium are bacteria that spread throughout your dog’s intestinal tract and is spread through contact with an infected dog’s feces.
Why is Clostridium perfringens bad?
Clostridium perfringens is bacteria that can infect the bowel in people and animals. The illness that results from a toxin produced by the bacteria is called Clostridium perfringens enteritis. Most people infected with these bacteria do not get severe illness. However, in rare cases the infection can cause symptoms.

Animals with acute disease (hemorrhagic gastroenteritis) merit appropriate antimicrobial therapy, although antibiotics are commonly administered even in cases of chronic diarrhea. Optimal antibiotics for the treatment of canine C perfringens–associated diarrhea include ampicillin, metronidazole, and tylosin.
What is Clostridium perfringens in dogs?
