A 25-year-old man was examined for tinea corporis. Microscopic examination of direct 10% KOH mount of skin scraping revealed the presence of hyaline, septate, branching hyphae. Cultures inoculated with portions of skin scrapings yielded, after two weeks Trichophyton simii. The identification of the fungus was based on colony morphology on mycobiotic agar and microscopic characteristics on slide cultures. Microscopic features of T. simii were cylindrical, 3-7 celled, thin-walled macroconidia. In older culture, macroconidia converted into chlamydospores, which is an important characteristic of T. simii.
一名25岁男性因体癣接受检查。对皮肤刮屑进行10%氢氧化钾直接涂片镜检，发现有透明、有隔、分支的菌丝。接种皮肤刮屑部分进行培养，两周后培养出西氏毛癣菌。该真菌的鉴定基于真菌琼脂上的菌落形态和玻片培养的微观特征。西氏毛癣菌的微观特征为圆柱形、3 - 7个细胞、薄壁的大分生孢子。在较老的培养物中，大分生孢子转化为厚垣孢子，这是西氏毛癣菌的一个重要特征。
