Tell me about c diff risk for elderly.?

High: As our immune system ages it less effectively fights infection. Clostrium difficile is a bacteria that often lives uneventfully in our GI tract. With the use of antibiotics, the normal bacteria in our large bowel is destroyed- c diff can then grow unchecked. C diff can also be spread by health care workers and other patients. It can be very serious and life threatening, especially in the elderly.
