  • This study is first report on dermatitis digitalis and dermatitis verrucosa, which were occurred in bovine claw, in the Republic of Korea. Pathologically, dermatitis digitalis was observed in the from of surperficial epidermitis on the skin at the caudal end of interdigital cleft with whitish epithelial bordel while dermatitis verrucosa in the form of wart-like proliferation of the skin midway between the bulbs and adjacent to the coronary band. Histological finding of dermatitis verrucosa were noticeable parakeratotic hyperkeratosis of the epidermis, acanthosis, spongiosis of prickle cell layer and intercellular bridges.

  • Clinically, three holstein dairy cattle showed the inappetence and decrease of milk production with severe lameness and pain. Grossly, strawberry-like proliferation of the skin between the heel bulbs were observed 4${\times}$5${\times}$1.5cm in size. Histopathologically, severe hyperplasia of epidermis, parakeratotic hyperkeratosis and multifocal ulceration of cornified cell layer, acanthosis, spongiosis of prickle cell layer and irregular arrangement of basal cell layer were seen. And focally observed the lesions of necrotic vasculitis, infiltration of inflammatory cells, congestion and hemorrhage. Spirochete bacteria were found in necrotic and outer proliferated epidermal cells by Levaditi's silver stain. Clinical and pathological findings were consistent with dermatitis verrucosa.

  • forty-five claw lamed cows with pododermatitis circumscripta, hyperplasia interdigitalis, and dermatitis verrucosa were treated surgically through resection of necrotic tissues, currettage, antibiotics application, and compressive bandage, under retrograde intravenous regional anesthesia of claw. At 7 days postoperation were showed lameness score 0, absense of swelling of extremitis, without fistulation and purulent exudate in wound. Mean duration time of action of local anesthetic drug was 75 minutes and mean operation time for treatment of pododermatitis circumscripta, hyperplasia interdigitalis, and dermatitis verrucosa was 35 minutes, 20 minutes, and 21 minutes, respectively.

  • During the period from june 1994 to february 1995 influence of free stall with concrete floor on profile of blood chemistry and clinico-morphopathogenesis of foot disease on 266 cows were studied. The results obtained as follow. 1. No differences between value of blood chemistry in normal and lame cows with foot disease were observed. 2. 20.7% of the cows were clinically lame. 3. Prevalence of clinical digital disorders were investigated: hyperplasia interdigitalis(45.8%), pododermatitis circumscripta(22.4%), dermatitis interdigitalis(9.4%), erosio ungulae(5.9%), phlegmona interdigitalis(3.5%), pododermatitis septica traumatica(3.5%), dermatitis digitalis(2.4%), white line disease(2.4%), pododermatitis aseptica diffusa(2.4%), dermatitis verrucosa(1.2%), fissura ungulae(1.2%) 4. Most claw lesions were located on lateral hindclaws and interdigital space of hindclaws.
