The purpose of this study was to investigate the contamination rates of Keratinophilic fungi in soils In Chonju. From september to November 1986, 98 soil samples were collected at the school and children's play ground, dog barn, pig barn, cow barn, horse barn and fowl barn( total 33 sites ). The samples were collected at the different depths(0～2cm, 30cm, 50cm ) in each of the sites, respectively. Each sample was cultured at 25$^{\circ}C$ according to Modified hair baiting method by using horse mane hair as a bait. The results obtained were summerized as follows ; 1. Eighty one of the 98 soil samples were found to be positive for Keratinophilic fungi. 2. In the examination of keratinophilic fungi in 98 soil samples, the organisms isolated weie as follows; Microsporum gypseum 20, Trichophyton ajelloi 15, Chrysosporium tropicum 40, C. Keratinophilum 24, C. tuberculatum 6 and Chrysosporium spp. like organism 4 strains. 3. The positive rates of keratinophilic fungi in each of the depths were 87.9%(29/33) in surface layer, 90.9%(30/33) in middle layer and 68.8％(22/32) in deep layer. 4. The positive rates of Keratinophilic fungi in each of the sites were 100%(3/3) in horse barn 91.7％ (l1/12) in dog barn, 88.9%(16/18) in pig barn, 86.7%(13/15) in cow barn, 76.2%(16/21) in fowl barn and 75.9%(22/29) in school and children's play ground. 5. The isolation rates of M. gypseum, Pathogenic fungi for human and animals, were as follows ; 58.3％ in dog barn(surface layers 100％, middle layers 50％, deep layers 25％) and 16.7％ in pig barn(surface 33.3％, middle 16.7%, deep 0％). In the cow barn, the isolation rates were 13.3%(surface 40.0％, middle 0%, deep 0％) and 10% in horse barn(surface l00％, middle 100%, depp 100%). In the fowl barn, the isolation rates was 19.1%(surface 28.8%, middle 14.3%, deep 14.3%) and 3.5% in school and children's play ground(surface 0％, middle 0％, deep 11.1%).
