　 来源：120online    　 日期：2007-05-07

　　【摘要】目的研究马拉色菌属的分类及其在一些皮肤病的分布情况。方法以标准株作对照，用生理生化学及形态学方法将150株来源于花斑癣（29株）、马拉色菌毛囊炎（16株）、脂溢性皮炎（49株）、甲真菌病（33株）及正常人皮肤（23株）的马拉色菌进行分类及描述，并分析了各菌种在一些皮肤病的分布情况。结果共分离出4个菌种：合轴马拉色菌65株、糠秕马拉色菌13株、钝形马拉色菌1株、球形马拉色菌71株。其中合轴马拉色菌和球形马拉色菌各占43.3％和47.3％；马拉色菌毛囊炎中全部为球形马拉色菌。结论此分类系统为经济、简便及可应用的马拉色菌属分类鉴定系统；球形马拉色菌与马拉色菌毛囊炎密切相关。

　　【Abstract】 Objective To study the taxonomy of Malassezia and distribution of the it in some dermatoses. Methods One hundred and fifty strains of Malassezia yeasts from pityriasis versicolor (29 strains), Malassezia folliculitis (16 strains), seborrheic dermatitis (49 strains), onychomycosis (33 strains), and healthy individuals(23 strains) were studied, according to physiological and morphological features in culture, and compared to standard strains. Results 4 species of Malassezia yeasts including M.sympodialis (65 strains), M.furfur (13 strains), M.obtusa (1 strain) and M.globosa (71 strains) were found, and M.sympodialis and M.globosa were accounted for 43.3％ and 47.3％ respectively. M.globosa were found in Malassezia folliculitis only. Conclusion The methods described in this study represent an economical, simple approach which is available for identification of Malassezia species. There is a close correlation between M.globosa and Malassezia folliculitis.
