Abstract

Previous treatment studies for papillomatous digital dermatitis (PDD) have found that recurrence of lesions is high and that treatment must be ongoing to control the disease. In a previous study we found that 18/22 lesions treated with lincomycin or oxytetracycline in a foot wrap appeared to be healed one month after treatment. When biopsies were examined we found that 10/18 (55%) of the lesions that appeared to be healed had some microscopic evidence of activity. We could not differentiate between lesions that were incompletely healed and those that were new infections. This study was designed to follow 30 cows with PDD for one year after treatment. Observations were to be made at monthly intervals.
