Fungi may cause lung disease through direct infection of pulmonary tissue, through infection of pulmonary air spaces/lung cavities, or through their ability to trigger an immunological reaction when fungal material is inhaled. The latter mechanism is involved in cases of allergic bronchopulmonary aspergillosis, aspergillus-induced asthma and hypersensitivity pneumonitis due to fungi (eg, maltworker's lung, farmer's lung). This article will concentrate on those diseases caused by direct fungal infection of the lung (fungal pneumonias).
