“…In Norway, Leucogyrophana holds 3% of the total number of wood-destroying fungi (Alfredsen et al 2005). L. pinastri, found under boards during a survey, was even blamed to be the cause of an extrinsic allergic alveolitis (Stone et al 1989). L. pulverulenta causes brown rot and occurs regularly in German buildings with earthy, wet substrates .…”

Wood is an important construction material, but when used incorrectly it can be subjected to deterioration by wood-destroying fungi. The brown rot producing dry rot fungus (Serpula lacrymans) is by far the most dangerous wood-destroying fungus in Europe. In the present publication, 645 fungal samples from damaged wood in the federal state of Styria (Austria) were examined and recorded by isolation date, geographical location, species identification of the wood-destroying fungus, location of damage, construction method, and age and type of building. In Styria, Serpula spp. accounted for 61.5% of damages, followed by Antrodia spp. (10.7%) and the genera Gloeophyllum (8.2%), Coniophora (3.9%) and Donkioporia (1.1%). Properties in the area of the Styrian capital Graz and old buildings were more often infested by wood-destroying fungi than houses in the rural area and new constructions.

“…One of the occupational groups at high risk of HP are workers exposed to wood dust, such as wood cutters, sawmill workers, furniture factory workers, carpenters and joiners [7]. Moreover, people exposed to wood dust at home while using wood chips as a fuel, remodeling wooden houses, or simply while exposed to rotten wood, may also develop HP [8][9][10][11]. To the best of the authors' knowledge, until recently at least 21 HP cases or groups of cases caused by the exposure to wood dust have been described.…”

Case description. Five workers (2 males and 3 females) employed in a furniture factory located in eastern Poland developed hypersensitivity pneumonitis (HP) after the pine wood used for furniture production was replaced by birch wood. All of them reported onset of respiratory and general symptoms (cough, shortness of breath, general malaise) after inhalation exposure to birch dust, showed crackles at auscultation, ground-glass attenuations in HRCT examination, and lymphocytosis in the BAL examination. The diagnosis of acute HP was set in 4 persons and the diagnosis of subacute HP in one. Identification of specific allergen. Samples of birch wood associated with evoking disease symptoms were subjected to microbiological analysis with the conventional and molecular methods. Two bacterial isolates were found to occur in large quantities (of the order 10 8 CFU/g) in examined samples: Gram-negative bacterium of the species Pantoea agglomerans and a non-filamentous Gram-positive actinobacterium of the species Microbacterium barkeri. In the test for inhibition of leukocyte migration, 4 out of 5 examined patients showed a positive reaction in the presence of P. agglomerans and 2 in the presence of M. barkeri. Only one person showed the presence of precipitins to P. agglomerans and none to M. barkeri. In the inhalation challenge, which is the most relevant allergological test in the HP diagnostics, all patients reacted positively to P. agglomerans and only one to M. barkeri. The results indicate that P. agglomerans developing in birch wood was the main agent causing HP in the workers exposed to the inhalation of dust from this wood, while the etiologic role of M. barkeri is probably secondary. Conclusion. The results demonstrate that apart from fungi and filamentous actinobacteria, regarded until recently as causative agents of HP in woodworkers, Gram-negative bacteria and non-filamentous actinobacteria may also elicit disease symptoms in the workers processing wood infected with large amounts of these microorganisms. The results obtained also seem to indicate that cellular-mediated reactions are more significant for causing disease symptoms compared to those that are precipitin-mediated.
