Foot rot, detection

Foot rot is the most common claw disease in sheep. It occurs with milder forms in goats, cattle, and wild ruminants, which contribute to the spread of the pathogen. Foot rot is globally widespread and is associated with considerable economic losses. Merino and Texel sheep as well as Suffolk are particularly susceptible. The disease is primarily caused by the bacterium Dichelobacter nodosus. An infection can cause great pain and is then associated with long-lasting suffering. Depending on the severity of the inflammation on the sole and wall horn and the damage to the dermis up to all limbs, the sheep may no longer walk in extreme stages; a typical manifestation of the disease is the atypical kneeling. Passive waiting by the owner is not compatible with §2 of the Animal Welfare Act. Swab samples of the interdigital cleft are analysed for Dichelobacter using PCR. Treatment with claw baths must be supported by a consistent hoof care. The use of a commercially available vaccine can also favour healing and reduce the potential of new infections.
