A NEW SPECIES, TRICHOSPORON DOMESTICUM, ISOLATED FROM THE HOUSE OF A SUMMER-TYPE HYPERSENSITIVITY PNEUMONITIS PATIENT IN JAPAN

A new species, Trichosporon domesticum Sugita, Nishikawa et Shinoda, i s proposed for a strain isolated from the house of a summer-type hyper sensitivity pneumonitis patient in Kumamoto, Japan. The nuclear DNA of T, domesticum showed intermediate relatedness to that of T. montevide ense; however, their genome sizes were significantly different. These findings suggest that they represent separate species. T. domesticum i s distinguished from T. montevideense by its inability to assimilate D arabinose, ribitol, and dulcitol. The type strain of T, domesticum is strain M 9401, which has been deposited in the Japan Collection of Mic roorganisms as JCM 9580.
