Sensitization to recombinant Aspergillus fumigatus allergens in allergic fungal sinusitis.

Background: Allergic bronchopulmonary mycosis is primarily caused by Aspergillus fumigatus. Despite similarities, allergic fungal sinusitis (AFS) is thought to be caused by various fungi.

Objective: Identify fungal elements in AFS allergic mucin and determine the prevalence of specific immunoglobulin (Ig)E to recombinant A.
