Enzyme immunoassay (EIA) for glutamate dehydrogenase (GDH) can be used as screening tool for patients with Clostridioides difficile infection. The enzyme is expressed constitutively by most strains of C.diff, and can thus be easily detected in stool. Diagnosis is generally confirmed with a follow-up EIA for C. Diff toxins A and B.

Clostridioides difficile toxin A (TcdA) is a toxin produced by the bacteria Clostridioides difficile, formerly known as Clostridium difficile. [1] It is similar to Clostridioides difficile Toxin B . The toxins are the main virulence factors produced by the gram positive , anaerobic, [ 2 ] Clostridioides difficile bacteria.
[39] [40] The protective effects of serum albumin may be related to the capability of this protein to bind C. difficile toxin A and toxin B, thus impairing entry into enterocytes. [40] Chronic kidney disease (CKD) has been identified as a risk factor in the development of a C. difficile infection.
There are different plasmid sizes of C. difficile. The detected molecular weights range from 2.7x10 6 to 100x10 6, but plasmid sizes show no correlation with toxicity. In order to detect the toxin B level in C. difficile, clinicians extensively use cell culture assays derived from stool specimens from patients with PMC.
Clostridioides difficile (syn. Clostridium difficile) is a bacterium known for causing serious diarrheal infections, and may also cause colon cancer. [4] [5] It is known also as C. difficile, or C. diff (/ s iː d ɪ f /), and is a Gram-positive species of spore-forming bacteria. [6]
A new report by the Clean Label Project has found that protein powders may contain something other than muscle-building nutrients: lead and cadmium, both of which are toxic.. The national ...
Clostridioides difficile infection, caused by the actions of the homologous toxins TcdA and TcdB on colonic epithelial cells is due to binding to target cells which triggers toxin internalization into acidified vesicles, whereupon cryptic segments from within the 1,050-aa translocation domain unfurl and insert into the bounding membrane ...
The major virulence factor of C. perfringens is the CPE enterotoxin, which is secreted upon invasion of the host gut, and contributes to food poisoning and other gastrointestinal illnesses. [3] It has a molecular weight of 35.3 kDa, and is responsible for the disintegration of tight junctions between epithelial cells in the gut. [6]
