Infection with Aspergillus spp. can be classified into allergic bronchopulmonary aspergillosis, aspergilloma, chronic necrotizing pulmonary aspergillosis, and invasive pulmonary aspergillosis. Airway colonization is associated with chronic airway disease and the isolation of Aspergillus spp. from a respiratory specimen does not indicate the presence of a clinically significant infection.
Aspergillus spp. are environmental fungi. They have a worldwide distribution, and inhalation of Aspergillus conidia is a common phenomenon. Aspergillus spp. can cause a variety of clinical syndromes that range from asymptomatic airway colonization to invasive pulmonary aspergillosis, depending on the immune status of the host.
