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.
Pathogenic C. difficile strains produce multiple toxins. [21] The most well-characterized are enterotoxin (Clostridium difficile toxin A) and cytotoxin (Clostridium difficile toxin B), both of which may produce diarrhea and inflammation in infected people, although their relative contributions have been debated. [20]
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.
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]
Bezlotoxumab, sold under the brand name Zinplava, is a human monoclonal antibody designed for the prevention of recurrence of Clostridioides difficile infections. [3] [4] Bezlotoxumab binds to Clostridioides difficile toxin B. [3]
