1) Trichoplyton rubrum No-6 formed spherical cells when cultured in brain heart infusion glucose liquid medium under continuous agitation at 37 C.
2) Five out of 15 strains of Trichophyton rubrum could form the spherical cells under this condition.
3) Pathogenicity for mice of the spherical cells was much greater than that of hyphae.
4) The spherical cells inoculated into mice intraperitoneally swelled in the lesions, and some of the swollen cells germinated.
5) In both brain heart infusion liquid medium and Sabouraud liquid medium these spherical cells could germinate at 37°C at 6 hours after inoculation but not at 27°C.
