“…This is a matter of considerable therapeutic and prophylactic variability among transplant centers. A variety of factors predispose to development of serious bacterial or fungal infections after transplant (55,56), including PGD, cytomegalovirus infection (57, 58), multiple transfusions (30,32), colonization with multiresistant organisms before transplant (59-62), enhanced or extensive immune suppression, renal failure, or episodes of acute rejection. Unfortunately, as therapeutic options for viral infection have improved, fungal organisms predominate, with an incidence of 15 to 35% (56,63).…”
