Clinical aspects of an outbreak of papillomatous digital dermatitis in a dairy cattle herd

Digital skin lesions and lameness of several weeks duration, with a morbidity rate of 28.3%, was reported in a group of 60 Holstein-Israeli dairy cows in various stages of lactation. A clinical survey was performed to monitor recovery and to confirm eradication of bovine papillomatous digital dermatitis in the herd. The combined effects of intensive individual treatment of the 4 lame cattle with procaine penicillin and metronidazole, and subjecting all animals in the herd to a foot bath with a solution composed of formaldehyde and sodium hydroxide twice a week for 12 weeks, were found to achieve a dramatic positive response in all affected cows in the herd. During a 1-year follow-up period no recurrence and/or new cases have been diagnosed.
