Isolation and identification of Neosartorya species from house dust as hazardous indoor pollutants

Abstract

Isolation of ascomycetous microfungi from 58 house dust samples from detached and apartment dwellings around Kobe City revealed that species of Talaromyces, Eurotium and Neosartorya were common ascomycetous propagules in the house dust. Neosartorya species accounted for 8.3% of the total identified isolates, of which N. pseudofischeri was the main constituent, indicating that it may be a common potential fungal pathogen in the dwelling environment. Based on the specimens collected, N. pseudofischeriis described and illustrated as new to Japan.
