Potted plants in hospitals as reservoirs of pathogenic fungi

Abstract

The soils of five potted plants cultivated within a hospital were investigated for the presence of fungal opportunistic pathogens of humans. A total of 16 potentially pathogenic species were isolated, including Aspergillus fumigatus at up to 53.5 colony-forming units (CFU) per gram dry soil and Scedosporium apiospermum (Pseudallescheria boydii) at up to 97.0 CFU/g. Other common species included Phialophora verrucosa and Fusarium solani. Scedosporium inflatum, a recently described emerging pathogen, is reported for the first time from an environmental source. The results of this study, in combination with previous case reports linking mycoses to potted plants and available information on the establishment and dispersal of fungal opportunistic pathogens in indoor habitats, indicate that indoor plant soils constitute a serious mycotic hazard to the immunosuppressed patient.
