Overview

Aspergillosis is caused by the fungus Aspergillus, commonly A. fumigatus. Aspergillus is ubiquitous in the environment.

Causes

Aspergillosis is caused by the fungus Aspergillus: Common Aspergillus species involved in human disease include the following:

Taxonomy

Eukaryota; Fungi/Metazoa group; Fungi; Ascomycota; Pezizomycotina; Eurotiomycetes; Eurotiales; Trichocomaceae; mitosporic Trichomaceae

Reservoir

  • Aspergillus is ubiquitous in the environment.
  • Aspergillus can be found in soil, decomposing plant matter, household dust, building materials, plants, food, and water.

Transmission

  • Transmission occurs through inhalation of airborne conidia.
  • Hospital-acquired infections may be sporadic or may be associated with dust exposure during building renovation or construction.
  • Occasional outbreaks of cutaneous infection have been traced to contaminated biomedical devices.

Incubation Period

The incubation period for aspergillosis is unclear and likely varies depending on the dose of Aspergillus and the host immune response.

Associated Diseases

Aspergillus may cause any of the following clinical syndromes depending on the host immune responses:

  • Allergic bronchopulmonary aspergillosis
  • Allergic Aspergillus sinusitis
  • Aspergilloma
  • Chronic pulmonary aspergillosis
  • Invasive aspergillosis
  • Cutaneous aspergillosis
