clostridium perfringens is an important cause of bacterial food poisoning worldwide. the disease is caused by c. perfringens enterotoxin (cpe) encoded by cpe gene. the aim of this research was to identify the different types of c. perfringens and the presence of cpe gene in isolated bacteria from broilers’ meat marketed in retail meat shops of mashhad city in northeastern of iran. after isolati...

Clostridium perfringens enterotoxin (encoded by the cpe gene) contributes to several important human, and possibly veterinary, enteric diseases. The current study investigated whether cpe locus organization in type C or D isolates resembles one of the three (one chromosomal and two plasmid-borne) cpe loci commonly found amongst type A isolates. Multiplex PCR assays capable of detecting sequence...

Clostridium perfringens type A isolates carrying the enterotoxin (cpe) gene are important causes of both food poisoning and non-food-borne diarrheas in humans. In North America and Europe, food poisoning isolates were previously shown to carry a chromosomal cpe gene, while non-food-borne gastrointestinal (GI) disease isolates from those two geographic locations were found to have a plasmid cpe ...

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. In the present study, the plasmid cpe locus of the type A non-food-borne-disease isolate F4969 was sequenced to design primers and probes for comparative PCR and Sou...

Clostridium perfringens enterotoxin (CPE) is a major virulence factor for human gastrointestinal diseases, such as food poisoning and antibiotic associated diarrhea. The CPE-encoding gene (cpe) can be chromosomal or plasmid-borne. Recent development of conventional PCR cpe-genotyping assays makes it possible to identify cpe location (chromosomal or plasmid) in type A isolates. Initial studies f...

BACKGROUND The choroid plexus epithelium (CPE) is a lobed neuro-epithelial structure that forms the outer blood-brain barrier. The CPE protrudes into the brain ventricles and produces the cerebrospinal fluid (CSF), which is crucial for brain homeostasis. Malfunction of the CPE is possibly implicated in disorders like Alzheimer disease, hydrocephalus or glaucoma. To study human genetic diseases ...

Report of a human with a homozygous truncating null mutation of the Carboxypeptidase E (CPE) gene with endocrinological and neurological deficits prompted us to search for other mutations in the human CPE gene that might be linked to disease. We searched an EST database and identified from a small population of patients, a novel T to C single nucleotide polymorphism (SNP) in the CPE gene at bp9...

About 5% of Clostridium perfringens type A isolates carry the cpe gene encoding the C. perfringens enterotoxin. Those cpe-positive type A isolates are important causes of food-poisoning and non-food-borne cases of diarrheas in humans, as well as certain veterinary cases of diarrhea. Previous studies have determined that the enterotoxigenic type A isolates causing both non-food-borne human gastr...

Clostridium perfringens type A isolates producing enterotoxin (CPE) are an important cause of food poisoning and non-food-borne human gastrointestinal (GI) diseases, including antibiotic-associated diarrhea (AAD). Recent studies suggest that C. perfringens type A food poisoning is caused by C. perfringens isolates carrying a chromosomal cpe gene, while CPE-associated non-food-borne GI diseases,...

The prevalences of various genotypes of enterotoxin gene-carrying (cpe-positive) Clostridium perfringens type A in 24 different food poisoning outbreaks were 75% (chromosomal IS1470-cpe), 21% (plasmid-borne IS1470-like-cpe), and 4% (plasmid-borne IS1151-cpe). These results show that C. perfringens type A carrying the plasmid-borne cpe is a common cause of food poisoning.
