Dermatophytes in the Kanazawa Region

Abstract

A statistical study of the dermatophytes isolated at the Dermatology Department of Kanazawa University School of Medicine, Kanazawa, Japan over the years 1968-78 was presented. Of 3, 567 specimens from the patients with dermatophytoses, 1, 908 (53.5%) was positive for dermatophytes. Trichophyton rubrum (58.9%) and T. mentagrophytes (36.6%) were the predominant species; of lesser prevalence was Epidermophyton floccosum (2.3%), Microsporum canis (0.5%), T. schoenleinii (0.2%), T. violaceum (0.2%) and M. gypseum (0.05%). The relationship between the species and the site of the disease was as follows: 17 isolates were obtained from the scalp, consisting of 6 strains of T. rubrum, 4 of M. canis, 4 of T. schoenleinii and 3 of T. violaceum. Glabrous skin (excluding hands and feet) yielded 563 isolates, most of which were T. rubrum (493). Of the 1, 166 isolates from the skin of the hands and feet, 651 were T. mentagrophytes and 489 were T. rubrum. Of the 155 isolates from the nails, 130 were T. rubrum and 20 T. mentagrophytes.
