==Description==

An economically important disease causing lameness in sheep, is associated with under-running of the hoof and a characteristic 'odour'. Footrot is caused by [[Dichelobacter nodosus|''Dichelobacter nodosus'']] together with [[Fusobacterium necrophorum|''Fusobacterium necrophorum'']].

Moisture and trauma allow ''F. necrophorum'' to enter which aids bacterial penetration of the epidermis by ''D. nodosus'' resulting in [[Necrosis - Pathology|necrosis]] and [[Inflammation - Introduction| inflammation]].  

 

The first stage of the disease, '''scald''', involves moisture and trauma allowing ''F. necrophorum'' to enter. If ''D. nodosus'' is not present, the superficial damage can heal without any signs of lameness. However, the damage ''F. necrophorum'' causes aids bacterial penetration of the epidermis by ''D. nodosus'' resulting in [[Necrosis - Pathology|necrosis]] and [[Inflammation - Introduction| inflammation]] and sloughing of the hoof horn ('''footrot''').  

 

Carrier animals are a major source of infection and are difficult to find as they are often sub clinical cases.
