Studies on Distribution and Pathogenicity of Dermatophytes Isolated from Pet Dogs in Pusan Area

부산지방에서 사육중인 애완견으로부터 분리한 피부사상균에 관한 연구

This study were performed to distribution of dermatophytes isolated from pet dogs in Pusan area and pathogenicity of the isolates. During the period from March 1993. to April 1994, 201 pet dogs of house breeding were examined. The result of obtained were summarized as followes； 1. Isolation rate of dermatophytes were 4.7%(7/149) in no lesion and 23.1%(12/52) in lesion of dog's skin. 2. According to breeding conditions, isolation rate of dermatophytes were 1) 3.8% in no lesion and indoor breeding, 2) 16.7% in lesion and indoor breeding, 3) 13.5% no lesion and outdoor breeding, and 4) 37.5% in lesion and outdoor bleeding. 3. Among the 201 Pet dogs, 16 strains of M. cams(84.2%), 1 of M. gypseum(5.3%), and 2 of T. mentagrophytes (10.5%) were isolated. 4. For Pathogenicity test, one strain of each M. canis, M, gypseum, T. mentagrophytes isolated from skin lesions were inoculated to the skin of the posterior back of guinea pigs. All of dermatophytes tested were induced skin lesions. Among them, M. cams and T. mentagrophytes were more virulent than M. gypseum.
