An inhalation model of airway allergic response to inhalation of environmental Aspergillus fumigatus conidia in sensitized BALB/c mice.

Fungal exposure may elicit a number of pulmonary diseases in man, including allergic asthma. Fungal sensitization is linked to asthma severity, although the basis for this increased pathology remains ambiguous. To create conditions simulating environmental fungal allergen exposure in a human, nose-only inhalation delivery of Aspergillus fumigatus conidia was employed in mice previously sensitized to Aspergillus antigen extract.
