Clostridium difficile toxin B is a toxin produced by the bacteria Clostridium difficile. C. difficile produces two major kinds of toxins that are very potent and lethal; an enterotoxin (Toxin A) and a cytotoxin (Toxin B, this protein). Early studies suggested that toxin A (also known as TcdA) is the major toxin protein causing antibiotic-associated diarrhea (AAD); however, within the last decade it has been shown that Toxin B (or TcdB) plays a more important role in disease than anyone had forecasted. Toxin B has been identified as the major virulence factor that causes the opening of tight junctions of intestinal epithelial cells, which enables toxin to increase vascular permeability and induce hemorrhaging.
