Lung inflammation measured in mice exposed to Aspergillus versicolor spores from a moisture-damaged building

Mice exposed to Aspergillus versicolor spores collected from a moisture-damaged building showed dose-dependent acute lung inflammation that persisted at higher doses.

How to read this

This library reports what studies found. An entry describes a study's design, its findings in its own terms, and its limits. Nothing here is a claim about what a Sage Co. home does, delivers, or prevents.

Last reviewed August 30, 2026.

What they studied

  • Aspergillus versicolor spores isolated from the indoor air of a moisture-damaged building.
  • Intratracheal instillation into mice at graded doses.
  • Measurement of inflammatory cells, cytokines, and lung histopathology over 28 days.

What they found

  • Dose-dependent acute inflammatory responses were reported in the exposed animals.
  • At higher doses, inflammatory changes were reported to persist beyond 28 days.
  • The spores used were building isolates rather than laboratory reference strains.

What this study does not establish

  • An animal instillation study; exposure route and dose differ from occupant inhalation.
  • Single fungal species tested in isolation.
  • No human outcomes measured.
  • This entry reports the study. It is not a statement about any building Sage Co. designs or constructs.
