| Cohort | A. fumigatus wild type and OErsmA strains were assessed in a lung infection model of invasive aspergillosis. Briefly, female Swiss ICR mice (Harlan Sprague Dawley) weighing about 18–20 g were immunosuppressed via administration of cyclophosphamide by separate intraperitoneal injections, one at 4 days (200 mg/kg of body weight) and the other at 1 day (200 mg/kg) before infection. |

| Disease Introduction Mechanism | Aspergillus fumigatus is an opportunistic pathogen of immunosuppressed individuals. In immunosuppressed hosts, invasive aspergillosis (IA) represents a major cause of morbidity and mortality, with mortality rates ranging from 40% to 90%. Part of the virulence of A. fumigatus is associated with its ability to produce a variety of toxic natural products. The natural product pathways in fungi result in the production of structurally diverse and low- molecular-weight compounds referred to as secondary metabolites (SMs). Although the functions of many fungal SMs remain to be determined, the known SMs of the genus Aspergillus have a tremendous impact on society. |
