Drug-resistant organisms are common in fecal surveillance cultures, predict bacteremia and correlate with poorer outcomes in patients undergoing allogeneic stem cell transplants.

Organisms resistant to 3rd generation cephalosporins are frequently seen on fecal surveillance in the pre-transplant setting and are associated with a higher incidence of drug-resistant organisms in subsequent blood cultures (not limited to the same drug resistance pattern as seen in fecal surveillance). Drug-resistant organisms in fecal surveillance are associated with poorer outcomes following allogeneic stem cell transplant and may be used as a guide to identify patients at risk of subsequently developing a drug-resistant organism in blood.
