The increase in immunosuppression, caused by disease or chemotherapy, has led to the appearance of infections caused by novel opportunistic fungi. These species include some that are well-known pathogens, such as Histoplasma capsulatum and Penicillium marneffei, which have a greater pathogenic effect in immunosupressed patients. In addition, relatively unknown pathogens such as species of Trichoderma, Malassezia, Acremonium, Exophiala and Curvularia, and members of the Mucoraceae including Apophysomyces elegans and Cunninghamella bertholletiae among others, have been reported occasionally as agents of systemic mycoses. Neutropenia is a major factor that promotes the development of opportunistic mycoses. However there are several other predisposing conditions, especially some which are iatrogenic. The epidemiological impact of antifungal resistance among opportunistic fungi is unknown. The commonest opportunistic mycoses are those caused by Candida species, including species different of C. albicans, and by species of Trichosporon and Fusarium which are considered the «more emergent» pathogens. Physicians and mycologists need to work together so that they can describe the isolation of rare fungal species, make a rapid diagnosis, and be able to begin an effective treatment.
