[Infectious causes of lameness in sheep - treatment options in veterinary practice]

Lameness in sheep induced by infectious agents can cause problems regarding animal welfare, diagnosis and treatment. Individual lame animals and lameness caused by systemic disease, but especially flock problems due to infectious causes of lameness, such as foot rot, can for various reasons pose a problem for veterinary treatment. The causes of lameness in sheep are described with a special focus on infectious flock problems, and the different treatment options such as foot trimming, foot baths and local and systemic antibiotic therapy as well as vaccination are discussed based on a review of recent international research. The limited choice of drugs licensed for use in sheep in Germany is highlighted. Treatment, therefore, often requires off-label use or the import of footbathing agents licensed in other European countries. The legal consequences of this lack of nationally licensed veterinary products in dealing with a "minor species" are discussed, with a final call for political solutions that will help improve this unsatisfactory situation.
