A review of footrot in sheep: aetiology, risk factors and control methods.

Abstract

Footrot is one of the major causes of lameness in sheep, goats and other ruminants. It is at times a highly contagious disease resulting from mixed bacterial infection with Dichelobacter nodosus as a necessary component. Disease manifestation can range from low to high prevalence depending on host, bacterial, environmental and climatic conditions, resulting in benign, intermediate and virulent forms of footrot. Accepted control methods include eradication of non-benign disease from affected flocks, control largely through vaccination, topical and systemic treatment and preventative measures through strategic vaccination. Not all forms of footrot warrant control or eradication since the cost of such preventative measures may outweigh the impact and cost of diseases as in the case of benign footrot.
