''D.nodosus'' is formerly known as ''Bacteroides''. It is a pathogenic, anaerobic, non-spore-forming Gram-negative bacteria. It causes [[Contagious Footrot|footrot]] in sheep, along with other bacteria.

Thermostable proteases and elastase contribute to the pathogenesis of ''D.nodosus''. Keratinolytic proteases are required for virulence and fimbriae are required for adhesion to hoof.

''D.nodosus'' is a primary pathogen of epidermal tissues of the hoof of ruminants, suriving briefly in the envionment. It can be passed from animal to animal.

==Immunity==

==Immunity==

A Homologous antibody to the fimbrial antigen prevents adhesion and protects against ''D.nodosus''. The antibody must penetrate the epidermal layers and reach adequate concentration on the skin surface. A vaccine is available against ''D.nodosus''. Strains can be detected by ELISA and PCR.
