[Contamination of archives by filamentous fungi and their evaluation for potential pathogenicity].

The results of microbiological examinations of dust samples collected from mortgage registers in the court archives are presented. In the samples examined filamentous fungi of Penicillium genus were observed as well as Cladosporium herbarum, Geotrichum candidum, Cephalosporium glutineum, Mucor racemosus, Trichoderma viride and Aspergillus niger. Filamentous fungi of Penicillium genus occurred in the highest concentration accounting for 350,000 CFU/g. The levels of the remaining fungi were lower--they ranged from 500 CFU/g to 100,000 CFU/g. The concentration of filamentous fungi observed in archives can create health risk for workers.
