Dermatophytes and Keratinophilic Fungi Isolated from Wild Rodents in Korea / 대한의진균학회지

ABSTRACT

BACKGROUND: Animals with zoophilic dermatophytes are important sources of dermatophytoses in man, because zoophilic dermatophytes are frequently transmitted directly or indirectly from domestic and wild animals. Trichophyton(T.) mentogrophytes has a wide range of hosts. Among these, rodents are well-known reservoirs in many other countries. In our country a few sporadic reports of incidence in experimental rats have been reported, but there is no study on the incidence in wild rodents in Korea. OBJECTIVE: The purpose of this study is to investigate the role of wild rodents as a host of dermatophytes and keratinophilic fungi in Korea. METHODS: Forty-nine wild rodents (Apodemus(A.) agrarius; 44, Crocidura spp; 5) were captured from 6 different regions of Kyungi-do with Sherman traps. Fungi were isolated by using the Mackenzie's brush technique. RESULTS: 1. Isolation rate of dermatophytes from wild rodents in Korea was 16.3%. 2. T. mentagrophytes was isolated from six A. agrarius (12.2%). Isolation rates from dorsum hairs, ventral hairs and feet were 4.5%, 9.1% and 9.1% respectively 3. Other dermatophytes and related keratinophilic fungi isolated were Chrysosporium spp.(65.3%), Scopulariopsis spp.(10.2%) and T. terrestre(4.1%). 4. Chrysosporium. was the most frequently isolated species from four out of six Kyonggi-do regions ranging 58.3%~83.3%. Scopulaiopsis was isolated the most in Kumgwang-myun Ansung-gun, and T. terrestre in Kimpo-gun. CONCLUSION: These results suggest that wild rodents, especially A. agrarius may be the important reservoirs of T. mentagrophytes and other keratinophilic fungi in Korea.
