Trichophyton mentagrophytes is the second common dermatophyte in Korea. However, few reports have been issued on the epidemiological and mycological characteristics of T. mentagrophytes in Korea based on long-term, large-scale study. The purpose of this study was to elucidate the epidemiological and mycological characteristics of T. mentagrophytes in Korea. During the 21-yr-period from 1992 to 2012, 6,250 patients with T. mentagrophytes were surveyed to determine annual incidence and the distribution of subjects by age, sex, season, involved sites, and place of residence. T. mentagrophytes infections were confirmed by fungal culture. In addition, the colony appearance of T. mentagrophytes was classified as granular, persicolor, powdery, or downy. Epidemiological analysis showed that annual incidence reached a peak in 2005, and then gradually decreased. T. mentagrophytes infection was most common in July, and was found predominantly in middle-aged adults, especially in those in their forties. Mycological analysis showed a powdery colony appearance was the most common, followed by persicolor and granular colonies. Toewebs were most frequently involved. This investigation on T. mentagrophytes provides insights into its incidence and characteristics.
须癣毛癣菌是韩国第二常见的皮肤癣菌。然而，基于长期的大规模研究，有关韩国须癣毛癣菌的流行病学和真菌学特征的报道甚少。本研究旨在阐明韩国须癣毛癣菌的流行病学和真菌学特征。在 1992 年至 2012 年的 21 年间，对 6250 例须癣毛癣菌患者进行了调查，以确定年度发病率以及按年龄、性别、季节、受累部位和居住地划分的患者分布情况。通过真菌培养来确认须癣毛癣菌感染。此外，还将须癣毛癣菌的菌落外观分为颗粒状、多彩状、粉状或绒毛状。流行病学分析显示，年度发病率在 2005 年达到高峰，随后逐渐下降。须癣毛癣菌感染最常见于 7 月，主要发生在中年成年人中，尤其是 40 多岁的人群。真菌学分析显示，粉状菌落外观最为常见，其次是多彩状和颗粒状菌落。脚趾间是最常受累的部位。这项对须癣毛癣菌的调查深入了解了其发病率和特征。
