Abstract
On July 5, 2005, samples of airborne fungi growing in the house of a patient with pulmonary aspergillosis in Nagasaki city, Nagasaki prefecture were taken for investigation. Sampling of the airborne fungi was conducted by using an air sampler (SAS SUPER 100, PBI) in the living room of the first floor and the bedroom of the second floor. Samples from ten places in each room were taken using a DG-18 medium (100L suck).
As a result, the mean value of the airborne fungi density was 634±100.6 CFU/m3 in the living room, and 1220±1853.9 CFU/m3 in the bedroom. Both Cladosporium and Mycelia sterilia accounted for about 70% of the fungi in the living room as a result of identifying isolates, while in the bedroom about 70% of the fungi was Aspergillus. Moreover, the ratio of Aspergillus in which A. fumigatus was the causal fungi of pulmonary aspergillosis was close to 100%. These figures suggest that the resident is inhaling A. fumigatus on a daily basis.
