The objective of the current study is to investigate the distribution of Keratinophilic and dermatophytic fungi. Material and method: Fungi in the surround-Soil of Babol Medical University’s hospitals during a three-month period from April to June of 2005. Samples were collected from 5-Cm depth of dry soil then processed by routine mycological methods for isolation of dermatophyte fungi by hair biting and plated onto S and SCC mediums. Results and conclusion: The obtained results were analyzed by means of the statistical package SPSS. The highest numbers of isolated keratinophilic fungi in percentage were as follows: Cunninghamella Spp (100%) from Shahyd Beheshti Hospital of Babol, Microsporum gypseum (100%) from Shahyd Yahyanejhad Hospital of Babol, M. gypseum (geophilic dermatophyte) (100%) from Kaboli Hospital of Babol, Microsporum gypseum (93%) from Children Hospital of Amirkola, Cunninghamella Spp (86%) from Marzikola Hospital of Babol, Aspergillus niger (53%) from Shahyd Rajaee Hospital of Babolsar. In addition, the highest and lowest number of mites and larves were found in Rajaee Hospital of Babolsar and Shahyd Yahyanejhad Hospital of Babol, respectively. The most commonly fungi isolated in this study was Cunninghamella Spp, followed by M. gypseum, as well as the least of them like Trichotechium spp, Alternaria spp and non-Candida yeasts. In the meantime, other common species were A. flavous, Mucor, Penicillium, Fusarium, and A. niger, M. gypseum, Drechslera, Gliocladium, A. fumigatus and Rhizopus sp.
