[Results of an airborne spore study in various regions of southern Sardinia].
Fungal air spores can play a significant role in several allergic manifestations. Therefore, the identification of geographic areas of mould distribution could be helpful to the clinician, especially if associated with fungal air spore recording in homes or working environments of sensitized subjects, in determining the real clinical importance of sensitization to fungi. On this basis, we studied the occurrence of airborne fungi at two urban sites and at two rural sites in the South of Sardinia, from May 1987 to April 1988, using the gravity plate method. Our survey has pointed out a significant difference about the occurrence of airborne spores in the areas sampled. Spore concentrations were lower at the urban sites during all the survey period. On the whole 6319 fungal colonies belonging to 28 different genera have been found. Cladosporium, Alternaria, Penicillium and Aspergillus, represented by a range of species, were the most common fungi identified in all sites examined. Remarkable the incidence of Yeasts, represented by the genera Candida, Saccharomyces, Rhodotorula and Sporobolomyces. Aureobasidium, Stemphilium, Botrytis, Chaetomium, Mucor and Rhizopus have been found in all sites but they have not been steadily isolated during the survey. Several other genera have been found only sporadically. Our results seem to confirm that fungal air spores, because of its quantity and variety, can represent a serious problem for human health in Sardinia.
