Clostridium difficile, also known more commonly as C. diff, accounts for 10 to 20% of<unk>  cases, because the<unk> s administered for the treatment of certain disease processes such as inflammatory colitis also inadvertently kill a large portion of the gut flora, the normal flora that is usually present within the bowel. With this lower level of "healthy" bacteria present, the overgrowth of C. diff is then responsible "for elaborating the enterotoxin".
