Pathogenesis
A. fumigatus is the most frequent cause of invasive fungal infection in immunosuppressed individuals, which include patients receiving immunosuppressive therapy for autoimmune or neoplastic disease, organ transplant recipients, and AIDS patients. A. fumigatus primarily causes invasive infection in the lung and represents a major cause of morbidity and mortality in these individuals. Additionally, A. fumigatus can cause chronic pulmonary infections or allergic disease in immunocompetent hosts.
