Background: Soil is one of the main habitat of fungi and important infection source of dermatophytosis. Objective: This study was performed to assess influence of dogs and horses to distribution ofkeratinophilic fungi (KPF) in soil. Methods: We visited 3 dog shelters and 3 horse riding grounds in Daegu and Kyeongbuk provincefrom September to November 2012 and examined isolation rates of fungi from 88 soil samples, 16 dogsand 16 horses. By the distance away from the animal shelters, soil samples were divided into 3 groupsconsist of near, 10 m and 100 m. Hair and scales from skin of the dogs and the horses were collected byMackenzie's brush technique. Results: Of the 88 soil samples examined, 35 (39.7%) yielded KPF and were all dermatophytesincluding Microsporum(M.) gypseum (34.1%) and Trichphyton(T.) ajelloi (5.6%). Isolation rates ofKPF from the soil were observed in 79.3% of near, 40% of 10 m, and 0% of 100 m from animal shelters. Of the 16 samples from dogs, 6 (37.5%) yielded positive dermatophyte cultures and they were identifiedas M. canis 31.2% (5/16) and T. eboreum 6.2% (1/16). Of the 16 samples from horses, 1 (6.2%) yieldedpositive dermatophyte culture and it was T. eboreum. Conclusion: In this study, isolation rates of KPF especially M. gypseum and T. ajelloi were higher inthe soil closer to the animal shelters. Soil nearby the dogs and the horses, the environment rich inkeratinous material, is conducive for the growth of dermatophytes. But M. gypseum and T. ajelloi thatrich in the soil were not isolated from skin of the dogs and the horses. Their pathogenicity might be low. We consider that if not human have immune deficiency or skin injury, they do not cause infection.
