Clostridium perfringens bacteria can be found in contaminated food that has been: cooked slowly; cooled too slowly; kept too warm in storage; reheated to a temperature that is too low; How food and water become .

Clostridium perfringens is a gram-positive, anaerobic, endospore-forming bacilli, often appear as boxcar shaped. It is mainly responsible for myonecrosis gas gangrenefood poisoning, and gangrenous cholecystitis.

Clostridium perfringens is a saprophyte in soil and also a commensal in the large intestine of human beings and animals. People get infected when the spores contaminate wounds from trauma.

Various manifestations include:. Other Clostridial infections are puerperal infections, anaerobic pleuropulmonary infections, and clostridial bacteremia. In what causes knots in your shoulders cases, C. Based on the clinical diagnosis of gas gangrene, treatment should be started as early as possible. Laboratory diagnosis has a role only for 1 confirmation of the clinical diagnosis, 2 species identification.

Laboratories can diagnose C. Serotyping of the isolates is done to determine if the same serotype of C. Gram-stained smears of aspirated material from myonecrosis reveal a necrotic background with a lack of inflammatory cells and presence of gram-positive bacilli with a morphology resembling C. Gram stained films provide clues about the species of clostridia present. Culture plates should be incubated anaerobically at 37oC for 2 days.

Clostridium perfringens do not produce spores in media routinely used in the what is the number to contact virgin mobile laboratory. Blood agar: After overnight incubation on blood agar, colonies are usually 1 to 3 mm in diameter, but may reach a diameter of 4 to 15 mm after prolonged incubation.

Colonies are usually flat, somewhat rhizoid, and raised centrally. Some colonies tend to spread, but they do not swarm.

On anaerobic blood agar, C. Opalescence can be inhibited by incorporating anti-alpha toxin to the medium. The test is also positive for other alpha toxin producing Clostridium ; C. Suspected C.
