The most common sources of bacteremia and serious bacterial infections in the elderly are the GU tract, the respiratory tract, and #3-the abdomen.
This third source is a bit of a surprise to many clinicians but worth remembering. Always consider the abdomen as the source of dangerous infections in the elderly when the source is not clearly the lungs or urine!
