Fusobacterium in Deer
(Fuso, Necrobacillosis, Fusobacterium necrophorum, lumpy jaw)
Fusobacterium is one of the most common disease causing bacteria in our deer industry. In deer, it can infect the skin, bone, mouth, jaw, hooves, and internal organs. Because of this, deer infected with Fusobacterium display a wide variety of clinical signs. Two of the more common signs are swollen faces (lumpy jaw) and lameness (foot-rot). Accurate diagnosis and treatment are imperative to overcome this terrible disease. There are commercially available and autogenous vaccines for Fusobacterium, but they provide minimal protection. These vaccines do, however, decrease the severity of the disease and reduce the contagiousness of the bacteria. Proper management is important to minimize disease. Keeping deer in a clean, minimal stress environment and not overcrowding them will decrease the spread of this disease. It is not recommended to purchase deer that have been diagnosed with Fusobacterium. Doing so could contaminate your farm and jeopardize your other deer.
