Antibiotic-associated pseudomembranous colitis has been shown to result from the action of these two toxins. This disease has been associated with clindamycin use but it is now recognized that pseudomembranous colitis can follow administration of virtually any antibiotic

Abstract. Clostridium difficile toxins A and B are major virulence factors responsible for induction of pseudomembranous colitis and antibiotic-associated diarrhea in men. The toxins possess a multidomain structure and only the N-terminal glucosyltransferase domain, which inactivates Rho GTPases by glucosylation, is translocated into the cytosol of target cells Biochem/physiol Actions Clostridium difficile Toxin A and B, cation-dependent UDP-glucose glucosyltransferases, are cellular toxins that inactivate Rho (and Rho family small GTPases) through monoglucosylation of these family members. Effects of this monoglucosylation include disregulation of the actin cytoskeleton, cell rounding, cytotoxicity, and altered cellular signaling Toxin A and B are capable of causing mucosal damage resulting in digestive tract inflammation leading to either clostridia difficile associated diarrhea (CDAD) or Pseudomembranous colitis (4). Toxin A is categorized as an enterotoxin, which means it is a toxin released by microorganisms that target the digestive system Clostridium difficile toxins A and B are the causative agents of pseudomembranous colitis. In even more cases, the toxins are responsible for antibiotic-associated diarrhea, which is a frequent complication occurring during or after therapy with antibiotics (1-3).Both toxins belong to the family of clostridial glucosylating toxins, which inactivate eukaryotic GTPases of the Rho family by.
