Abstract:
Hypersensitivity pneumonitis is a syndrome reported in humans, and occasionally animals, that results from the inhalation of very small antigenic particles (usually <5 µm) that are able to reach the alveolar space. This is the first report of hypersensitivity pneumonitis in a dog in Australia and the first associated with Geastrum triplex spores. Diagnosis was based on known antigen exposure, physical findings, radiographic signs of interstitial lung disease and molecular identification of Geastrum triplex in bronchoalveolar lavage fluid.
