Although the natural habitat of Trichosporon species is considered to be the soil, the role of normal skin in the carriage of Trichosporon beigelii is unknown. The purpose of this study was to determine the prevalence of T. beigelii colonization on normal perigenital skin. Inguinal skin scrapings were obtained from 322 asymptomatic volunteers. There were 261 males and 61 females ranging in age from 18 to 89; 136 were white, 134 were black, and 52 were Hispanic. Specimens were cultured on Sabouraud's glucose agar containing 500 micrograms ml-1 chloramphenicol, and incubated at 23-26 degrees C for up to 4 weeks. The overall incidence of T. beigelii colonization was 12.4%. However, this varied with patient's age, sex, race and socioeconomic background. The highest prevalence (27.1%) was found in black males who attended a Veterans Affairs hospital. The prevalence was lowest in females (1.6%), and no patients who attended a private clinic were colonized. It was concluded that T. beigelii colonizes normal skin with some regularity.
虽然丝孢酵母属的自然栖息地被认为是土壤，但正常皮肤在白吉利丝孢酵母携带方面所起的作用尚不清楚。本研究的目的是确定白吉利丝孢酵母在正常生殖器周围皮肤的定植率。从322名无症状志愿者身上获取腹股沟皮肤刮屑。其中有261名男性和61名女性，年龄在18至89岁之间；136人为白人，134人为黑人，52人为西班牙裔。将标本接种在含有500微克/毫升氯霉素的沙氏葡萄糖琼脂上，于23 - 26摄氏度孵育长达4周。白吉利丝孢酵母定植的总体发生率为12.4%。然而，这随患者的年龄、性别、种族和社会经济背景而有所不同。在一家退伍军人事务医院就诊的黑人男性中发现的患病率最高（27.1%）。女性的患病率最低（1.6%），且在私人诊所就诊的患者中无人定植。得出的结论是，白吉利丝孢酵母会有一定规律地定植于正常皮肤。
