Fungal flora in house dust in Riyadh, Saudi Arabia

Abstract

Fungi in the house-dust of houses in the less populated and densely populated areas of Riyadh, Saudi Arabia, were screened. The screened area included drawing rooms, living rooms, kitchens, bedrooms and bathrooms. A total of 74 fungal species were isolated. The highest number of fungal colonies were found in the living rooms followed by bedrooms. The number of fungal colonies isolated were higher in densely populated areas compared with less populated areas. Aspergillus was the predominant genus represented by highest number of species followed by Penicillium.
