PURPOSETo review the characteristics and evolution of the fungal spectrum, and the risk factors causing fungal infection, and to make progress in diagnosing fungal infection after organ transplantation.

DATA SOURCESAn English-language literature search (MEDLINE 1990 - 2000) and bibliographic review of textbooks and review articles.

STUDY SELECTIONTwenty-three articles were selected from the literature that specifically addressed the stated purpose.

RESULTSFungal infections in organ transplant patients were generally divided into two types: (1) disseminated primary or reactivation infection with one of the geographically restricted systemic mycoses; (2) opportunistic infection by fungal species that rarely cause invasive infection in normal hosts. The risk factors of fungal infection after a transplant can be evaluated and predicted according to the organ recipient's conditions before, during and after the transplant. Progress in early diagnostic methods during the past 10 years has mainly revolved around two aspects, culture and non-culture.

CONCLUSIONSIt is important to undertake a systemic evaluation on the condition of the organ recipient before, during and after a transplant; should any risk factor for fungal infection be suspected, diagnosis should be made as early as possible by employing mycological techniques including culture and non-culture methods.
