[From when on can fungi be identified in nasal mucus of humans?].

Background: Fungal spores are frequent in air and their occurrence in the nasal mucus appears to be a common finding within the adult population, as we were able to show in recent studies. 91,3 % of CRS patients but also healthy controls grew positive fungal cultures out of their nasal mucus. The potential role of fungal elements in nasal mucus for the pathogenesis of CRS, with or without polyposis, is currently investigated intensely and discussed very controversially.
