Infection control issues after bone marrow transplantation.

Bone marrow transplant recipients are at increased risk of a variety of infections from endogenous and exogenous sources. Various practices, including the use of prophylactic agents and a controlled environment are often employed in the name of infection control. Comparable data are lacking because of non-unified definitions of infection and endpoints. Antibiotic-resistant bacteria and fungi are being isolated more frequently as a result of selective pressure.
