Innebörden av infektion med Treponema spp. vid digital dermatit hos får samt likheter med bovin digital dermatit

Abstract: This literature study assembles current knowledge about CODD (Contagious Ovine Digital Dermatitis). The aetiology of this disease is not completely known and to obtain a manageable overview, this study aims to summarize the knowledge from published studies and shed light on the subject. Search for literature on the subject has been made in the Web of Knowledge, PubMed and Google Scholar, and has been compiled in this paper. Footrot and ovine interdigital dermatitis are differential diagnosis of CODD and they possibly have a common role in the emergence of CODD. Several studies have drawn parallels to bovine digital dermatitis. The close kinship between the Treponema spp. found in these diseases as well as its close relationship with the spirochetes found in human cases of periodontitis is discussed.
