Carboxypeptidase E (CPE) has important functions in processing of endocrine pro-peptides, such as pro-insulin, pro-opiomelanocortin, or pro-gonadotropin-releasing hormone, as evidenced by the hyper-pro-insulinemia, obesity, and sterility of Cpe mutant mice. Down-regulation of Cpe in enlarged placentas of interspecific hybrid (interspecies hybrid placental dysplasia (IHPD)) and cloned mice sugge...
Clostridium perfringens is an important anaerobic pathogen causing food-borne gastrointestinal (GI) diseases in humans and animals. It is thought that C. perfringens food poisoning isolates typically carry the enterotoxin gene (cpe) on their chromosome, while isolates from other GI diseases, such as antibiotic-associated diarrhea, carry cpe on a transferable plasmid. However, food-borne GI dise...
Enterotoxin-producing Clostridium perfringens type A isolates are an important cause of food poisoning and non-food-borne human gastrointestinal diseases, e.g., sporadic diarrhea (SPOR) and antibiotic-associated diarrhea (AAD). The enterotoxin gene (cpe) is usually chromosomal in food poisoning isolates but plasmid-borne in AAD/SPOR isolates. Previous studies determined that type A SPOR isolate...
We found a prevalence of 18% for enterotoxin gene-carrying (cpe+) Clostridium perfringens in the feces of healthy food handlers by PCR and isolated the organism from 11 of 23 PCR-positive persons by using hydrophobic grid membrane filter-colony hybridization. Several different cpe genotypes were recovered. The prevalence was 3.7% for plasmidial IS1151-cpe, 2.9% for plasmidial IS1470-like-cpe, 0...
Clostridium perfringens, one of the most common causes of food poisonings, can carry the enterotoxin gene, cpe, in its chromosome or on a plasmid. C. perfringens food poisonings are more frequently caused by the chromosomal cpe-carrying strains, while the plasmid-borne cpe-positive genotypes are more commonly found in the human feces and environmental samples. Different tolerance to food proces...
By virtue of its ability to regulate the composition of cerebrospinal fluid (CSF), the choroid plexus (CP) is ideally suited to instigate a rapid response to traumatic brain injury (TBI) by producing growth regulatory proteins. For example, Esophageal Cancer Related Gene-4 (Ecrg4) is a tumor suppressor gene that encodes a hormone-like peptide called augurin that is present in large concentratio...
OBJECTIVES The objective of this study was to evaluate in a multicentre survey the analytical performance of the Check-Direct CPE® assay (CDCPE), a multiplex PCR assay for the detection of carbapenemase-producing Enterobacteriaceae (CPE), directly from rectal swabs. METHODS Adult patients admitted to a high-risk unit in four participating centres were prospectively screened for CPE carriage b...
background and objectives: clostridium perfringens is more prevalent type of clostridia genus isolated from the intestinal tract of ostrich ( struthio camelus ). necrotic enteritis (ne) is a potentially fatal gastrointestinal (gi) disease of poultry and other avian species, which produces marked destruction of intestinal lining in digestive tract caused by c. perfringens . pathogenicity and les...
Using gene expression profiling, others and we have recently found that claudin-3 (CLDN3) and claudin-4 (CLDN4) are two of the most highly and consistently up-regulated genes in ovarian carcinomas. Because these tight junction proteins are the naturally occurring receptors for Clostridium perfringens enterotoxin (CPE), in this study, we used the COOH-terminal 30 amino acids of the CPE (CPE(290-...
Induction of the cytopathic effect (CPE) in cells infected with poxvirus seems ubiquitous in that it has been associated with all different strains and preparations of poxviruses, regardless of the replicating status of these viruses. The study of the mechanisms by which CPE is induced by nonreplicating poxviruses is hampered by the lack of any noncytopathic mutant strains and preparations. In ...
