Footrot is a contagious bacterial foot disease caused by Dichelobacter nodosus. Two major clinical forms of footrot have been described, benign and virulent. The benign footrot which is mild form of the disease is characterized by inflammation and degeneration of interdigital tissue. Virulent footrot is characterized by severe degenerative and necrotic damage of the epithelial tissue of the hoof. In this form, one or more foot exungulation can be seen. The severity of the disease depends on various factors such as the virulence of the D. nodosus strain, environmental conditions, farm applications and the susceptibility of the host animal. Footrot causes severe pain and lameness in affected sheep. Footrot and its associated lameness are the main causes of animal welfare and economic worries in countries where sheep and goat breeding are common. The disease has a great effect on herd productivity and profitability, leading to a decrease in wool yield, inadequate growth in lambs, decreased fertility in sheep, and limited sales opportunities for infected sheep. Future strategies for the eradication and management of the disease in many regions where the footrot is being studied in struggle with the footrot can be developed. These include developing specific vaccines, acquiring important information about the genetic structure of Dichelobacter nodosus, developing new management strategies specific to the environment, developing new genetic testing methods, and breeding trials to obtain disease-resistant animals. In this review, information has been given about footrot which is an important foot disease of sheep.
