Abstract

In an effort to investigate the additional changes of the dermatophytic flora in the Kanto districts (Tokyo and its neighborhood), the dermatophytic flora of the Dermatology clinic at Tokyo University Hospital and other two contributing institutes, the Division of Dermatology of Kanto Rosai Hospital and Iwashige Clinic of Dermatology, were surveyed in the last ten years. At the Dermatology clinic at Tokyo University Hospital for the last ten years from 1969 to 1978, the total number of 4, 030 patients (4, 106 cases) with dermatophytosis confirmed by mycological cultures, were obtained. 4, 106 cases consisted of 5 Tinea capitis, 382 Tinea corporis, 863 Tinea cruris, 2, 034 Tinea pedis, 212 Tinea manus, 559 Tinea unguium, 20 Tinea scroti, 15 Kerion celsi, 12 Sycosis parasitaria, two tinea faciei, each of agminate folliculitis type, and two trichophytic granuloma due to T. rubrum. The species and numbers of isolated strain were 2, 969 of T. rubrum, 982 of T. mentagrophytes, 84 of E. floccosum, 36 of M. canis, 15 of M. gypseum, 6 of T. violaceum, 4 of T. glabrum, 2 of T. verrucosum and 8 of unidentified dermatophytes. The following dermatophytes were cultured at the above three institutes during the period of study: T. rubrum (6, 527), T. mentagrophytes (2, 967), E. floccosum (272), M. canis (84), M. gypseum (53), T. violaceum (10), T. glabrum (6) and T. verrucosum (3).
