Background: Fungal contamination in indoor environments has been associated with various adverse health effects, particularly respiratory diseases. Methods. This study aimed to determine the populations of the fungal species related with four different floor types (rug, carpet, tile, and vinyl) in an indoor environment. A total of sixteen (16) samples were examined. The total fungal population was enumerated using the pour plate method on Potato Dextrose Agar. Results: The mean (mean ±STD) fungal population in the tile samples ranged from 4.0± 1.52 to 19± 1.52. The carpet samples ranged from 6.0 ± 4.16 to 19 ± 1.52; the vinyl samples ranged from 3.33 ± 1.52 to 16 ± 1.15. The rug samples ranged from 7.3 ± 1.152 to 18 ± 3.00. The analysis of variance (ANOVA) indicates positive and significant statistical differences between the fungal populations on the various floor types. In this study, seven different fungal species were identified: Penicillium spp, Yeast spp., Aspergillus spp., Rhizopus spp., Fusarium spp., Trichophyte spp., and Mucor spp. These species were detected in almost all the floor types. However, Fusarium spp. was not found on carpet floors, while Trichophyte spp.
