Abstract

Environmental fungi, moulds and yeasts could reach the nasal cavity with the inhaled air causing respiratory symptoms in atopic subjects, but little is known about the fungal flora of this site. In the present study samples of the nasal cavities of 135 subjects aged 18-35 years (48 allergic patients to fungi, mites and/or cat fur and from 87 normal subjects - healthy, control group) were cultured. All of them lived in the metropolitan area of Barcelona. Fungi were isolated from 41.5% of healthy people and in 14.8% of allergy patients (p = 0.011). Morphologically, 50.4% of the isolates were located within 4 genera: Cladosporium, Penicillium, Aspergillus and Alternaria, fungi which are considered the most allergenic. The most prevalent species were: Cladosporium herbarum and C. cladosporioides (23.6%). Alternaria alternata was isolated only in 8.8% of samples from the allergic group, although most subjects were sensitive to this species. There were not differences in the isolation rate between genera and smoking-no-smoking groups. The lower prevalence of nasal fungi from allergic patients could be related to the nasal insufficiency, the hypersecretion and the larger use of handkerchief. ©2007 Revista Iberoamericana de Micología.
