Clinical isolates of Trichosporon cutaneum, the causative agent of trichosporonosis, were identified on the basis of DNA relatedness. Of the 10 strains from deep-seated and mucosa-associated infections, 9 were identified as T. asahii and 1 was identified as T. ovoides. The two superficial strains were identified as T. cutaneum and a variety of T. montevideense. These findings suggest that T. cutaneum is a heterogeneous species in clinical samples and that the causative agents of trichosporonosis exist in four or more species.
皮肤毛孢子菌病的病原体——皮状毛孢子菌的临床分离株是根据DNA相关性来鉴定的。在从深部和黏膜相关感染中分离出的10株菌株中,9株被鉴定为阿萨希毛孢子菌,1株被鉴定为卵形毛孢子菌。两株浅表感染菌株被鉴定为皮状毛孢子菌和蒙特维的亚毛孢子菌的一个变种。这些发现表明,在临床样本中皮状毛孢子菌是一个异质物种,并且皮肤毛孢子菌病的病原体存在于四个或更多的物种中。
