[Prevention of infection after bone marrow transplantation].

Patients receiving allogenic bone marrow transplantation (BMT) always experience transient severe granulocytopenia and a defect of cellular and humoral immunity. Subsequently, the immune system is impaired in particular by acute or chronic graft-versus-host disease. The major measures employed for infection prophylaxis following bone marrow transplantation are described, and the results of our own studies presented and discussed.
