Papillomatous digital dermatitis (PDD) is a dermatosis of the digital skin of cattle, which, in recent years, has become one of the most important causes of lamness. Probably the direct causes of the disease are Treponema spp., Fusobacterium spp., Bacterioides spp. and Dichelobacter nodosus. PDD occurs on the hairy skin between the hooves and heels of hind limbs, where circumscriptes red plaques appear. Therapy requires the use of penicillin 18000 IU/kg every 12 h for 3 days or a topical application of oxytetracycline 20-100 mg/ml for 3 to 5 days and footbaths in solutions of 0.1 to 0.6% oxytetyracycline, 20% zinc sulfate, 0.01% lincomycin, 2.5 to 10% copper sulfate, and 5% formalin every 3-7 days. Interdigital dermatitis (ID) is triggered by the same bacteria as PDD and its course of therapy is the same. Acute attacks of the disease are characterized by epidermal erosion and superficial dermatitis in the interdigital skin, and, in chronic cases of ID, upper cracks and fissures of the horn. Dermatophilosis is a dermatosis occurring in cattle, sheep, goats and horses, caused by Dermatophilus congolensis. Bacteria provoke exudative inflammations of the skin and crust formation. Sheep may develop a form of dermatophilosis that begins as a proliferative dermatits in the cornet region, known as strawberry foot-rot. Lesions can extend from the hoof to the hock. Therapy requires the use of oxytetracycline in a single dose of 20 mg/kg or penicillin and streptomycin in doses of 70 000 IU and 70 mu g/kg for 3 days.
