WebIntroduction. Clostridium difficile infection (CDI) is a major nosocomial bacterial disease with nearly half a million cases, 29,000 fatalities, and 83,000 first recurrences in the United States in 2011. 1 The infection has been associated with a spectrum of clinical diseases ranging from mild, self-limited diarrhea to fulminant colitis and death in some cases. WebThe half-lives of different isotopes can be very differ-ent. Some parent isotopes have half-lives of more than 4 billion years. Others have half-lives of only about 6,000 years. Very old rocks can be dated only if isotopes with long half-lives are used. Very young rocks can be dated only if isotopes with short half-lives are used.
