Description
Between April 1991 and June 1992, 27 digital lesions, diagnosed as verrucose dermatitis and/or digital papillomatosis, were found in 18 cows from 3 dairy farms in Gunma Prefecture; 24 lesions were in the hind feet, 23 being in the plantar aspect, midway between the heel bulbs and adjacent to the coronary band. Topical application of antibiotic ointments or an oxytetracycline/gentian violet aerosol produced recovery, but a 5% formalin spray had no beneficial effects. Histological examination showed hyperkeratosis and parakeratosis of the epidermis and perivascular mononuclear cell infiltrations in the dermis. Spirochaetes were detected in the epidermis by the Levaditi silver impregnation method. Ultrastructurally the spirochaetes resembled Treponema, being 9 `m long and 0.2-0.4 `m wide with 8 coils and 10 axial fibres
