Summary. It is a perpetual threat to sheep flock lameness levels, health and welfare and ultimately productivity. Sheep will become slightly to moderately lame depending on the stage of infection. This condition is technically referred to as benign foot rot but has also been called foot “scald.” It is believed that the strains of D. nodosus that are involved are weak enzyme producers and are less able to produce the severe damage seen with virulent foot rot. In an infected flock, several strains of D. nodosus may be present. So, F. necrophorum is considered the cause of true foot scald disease and the facilitator of foot rot disease. Animals with severe foot rot might show fever, loss of appetite, with hoof deformity. If not present, only foot scald will occur.

The bacteria Fusobacterium necrophorumcauses a common disease known as foot scald. Hoof rot and hoof scald rarely occur in arid hot climates, even when goats are maintained in crowded conditions. This organism produces a powerful proteolytic enzyme that dissolves hoof horn and leads to the undermining of the sole, the severe lameness, the foul smell, and the abnormal hoof growth seen with classic virulent foot rot. Severe cases of foot rot may be accompanied by the presence of pus and a foul smell. In other words, what seems to be just “scald” in one flock, may be much more serious, and look like virulent foot rot, if it is introduced to another. Those flock owners who have experienced milder forms of lameness in their flocks may assume that they don’t have foot rot but have a milder condition called “foot scald” or “scald.” Actually there are really two recognized conditions that are sometimes referred to as “scald.” At first the difference may seem academic, but for some producers, it may be more than that.

Many times, placing sheep on drier footing and out of mud will alleviate the problems of the disease. Both D. nodosus and F. necrophorum can be isolated from these cases, but the strains of D. nodosus isolated seem have a reduced virulence or ability to produce disease.
