Aspergillus and other fungi.

Opportunistic infections that arise in the immunocompromised host are a major cause of morbidity and mortality. Although bacterial infections are more frequent, invasive fungal infections occur commonly and carry higher risks in these immunocompromised patients. Newer antifungal agents, along with an occasional pulmonary resection, have improved the treatment options and the survival from invasive fungal infections in immunocompromised patients.
