چکیده

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.

Phylogenetic group determination of faecal Escherichia coli and comparative analysis among different hosts

Phylogenetic analysis has shown that Escherichia coli is composed of four main phylogenetic groups (A, B1, B2 and D). Characterization of phylogenetic groups is of clinical interest, as group A and B1 generally associated with commensals, whereas most enteropathogenic isolates are assigned to group D, and group B2 is associated with extra-intestinal pathotype. One hundred E. coli strains recove...

Bird fanciers lung in mushroom workers.

Hypersensitivity pneumonitis has been described in mushrooms workers caused by exposure to mushroom or fungal spores in the compost used to grow mushrooms. We describe two mushroom workers who developed hypersensitivity pneumonitis due to exposure to avian proteins found in poultry manure which was used in producing mushroom compost. Both workers were employed in the compost production area. Bo...

Hypersensitivity pneumonitis: an overlooked cause of cough and dyspnea

Hypersensitivity pneumonitis (HP) is an immune-mediated pulmonary disorder involving inflammation of the lung interstitium, terminal bronchioles, and alveoli caused by the immune response to the inhalation of an offending environmental airborne agent. It can manifest as exertional dyspnea, fatigue, weight loss, and progressive respiratory failure if left untreated. Because of its protean featur...
