Clostridium difficile (C. diff)

 
Clostridium difficile is a germ that can cause diarrhea and inflammation of the colon or more serious conditions, such as pseudomembranous colitis. C. difficile has been most often related to health care settings; however, in recent years, more people have gotten these infections outside of health care settings. People who have other illnesses, are elderly, or who have been taking antibiotics are at greater risk of acquiring C. difficile.
