Clostridium perfringens type A isolates carrying a chromosomal enterotoxin (cpe) gene (C-cpe) are generally linked to food poisoning, while isolates carrying cpe on a plasmid (P-cpe) are associated with non-food-borne gastrointestinal diseases.
Clostridium perfringens type A isolates carrying an enterotoxin (cpe) gene are an important cause of human gastrointestinal diseases, including food poisoning, antibiotic-associated diarrhoea (AAD) and sporadic diarrhoea (SD).
Previous studies have determined that the enterotoxigenic type A isolates causing both non-food-borne human gastrointestinal disease and veterinary disease carry their cpe genes on plasmids, while the type A isolates causing human food poisoning carry a chromosomal cpe gene.
Clostridium perfringens type A isolates causing food poisoning have a chromosomal enterotoxin gene (cpe), while C. perfringens type A isolates responsible for non-food-borne human gastrointestinal diseases carry a plasmid cpe gene.
Recent studies have indicated that C. perfringens isolates associated with food poisoning carry a chromosomal cpe gene, while non-food-borne human gastrointestinal disease isolates carry a plasmid cpe gene.
