In 1935, Hall and O'Toole first isolated a gram-positive, cytotoxin-producinganaerobic bacterium from the stool of healthy neonates.1 Theynamed it Bacillus difficilis to reflect the difficulties theyencountered in its isolation and culture. We now face the oppositeproblem of being unable to contain the growth and spread ofthe same bacterium, now called Clostridium difficile, whichis a frequent cause of infectious colitis, usually occurringas a complication of antibiotic therapy, in elderly hospitalizedpatients. In this article we review recent changes in the epidemiologyof C. difficile infection, discuss changes in disease severityand response to therapy, . . . [Full Text of this Article]
