NJB Hoofcare Foul in the Foot (interdigital necrobacillosis) for St Briavels,, Forest of Dean, Gloucestershire
Foul-in-the-foot, also known as interdigital necrobacillosis or foot rot, is an acute and highly infectious disease of cattle characterised by swelling of the foot and resulting in lameness. This extremely painful condition can become chronic if treatment is not provided, allowing other foots’ structures to become affected.
Foul-in-the-foot occurs when the skin in between the claws becomes damaged and a bacterium called Fusobacterium necrophorum infects the soft tissue between the digits, although other bacterial species have been linked to the condition. A painful swelling of the foot between the claws and around the adjacent coronary band occurs rapidly and the inflammation may extend to the pastern and fetlock. Other symptoms caused by the illness include pain caused by the pressure of the swelling, severe lameness, fever, and a reduction in milk yield.
