What is C DIFFICILE TOXINS A AND B?
toxin B is a toxin produced by the bacteria. 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). Toxin B (TcdB) is a cytotoxin that has a molecular weight of 270 kDa and an isoelectric point, pl, of 4 ...

However, toxin A is not essential for virulence because virulent strains of C. difficile that are toxin A–negative but toxin B–positive have been described. The genes that encode toxins A, tcdA, and B, tcdB, are found on the pathogenicity locus in C. difficile.
Clostridium difficile is a spore-forming bacteria that is part of the normal intestinal flora. With intestinal overgrowth, C. difficile is the major cause of antibiotic-associated diarrhea and colitis secondary to antimicrobial therapy. C. difficile is the primary cause of pseudomembranous colitis.
