Foot rot in cattle is caused by the anaerobic bacteria ''[[Fusobacterium necrophorum]]''.
Foot rot in cattle is caused by the anaerobic bacteria ''[[Fusobacterium necrophorum]]''.
''Fusobacterium necrophorum'' is '''ubiquitous in the environment of cattle''' as it is a normal inhabitant of the intestine and faeces. <Kanoe, M., Imagawa, H., Toda, M (1975) '''Distribution of Fusobacterium necrophorum in bovine alimentary tracts.''' Bulletin of the Faculty of Agriculture, Yamaguti University, Japan, 26:161-172.</ref> It can also remain dormant in the soil for several months.<ref>Tulasne, J. J., Béguin, J. C (1982) '''Ovine Footrot: General report'''.''Proceedings of the 4th International Symposium on disorders of the ruminant digit, Paris, France''.</ref> The organism contaminates areas where cattle congregate.

Foot rot in cattle should '''not be confused with [[Footrot - Sheep|foot rot in sheep]]'''. The '''two diseases are different''' and cross infection between the two species is not believed to occur. Foot rot in sheep requires not only a virulent strain of ''[[Dichelobacter nodosus]]'' to be present, but also ''[[Fusobacterium necrophorum]]''.

Foot rot has been reported from many countries. The disease is particularly prevalent in temperate climates with a moderate '''rainfall''' and relatively high cattle population density.
