Isolation of filamentous fungi from sputum in asthma is associated with reduced post-bronchodilator FEV1.

This study was supported by the Midlands Asthma and Allergy Research Association (CHP, AJW, AF, REE), Asthma UK, Wellcome Trust Senior Fellowship (CEB) and the European Regional Development Fund (ERDF 05567). AJW has received grant funding from Pfizer Ltd for a clinical trial of voriconazole in fungal allergy-associated asthma.
