The occurrence of severe lameness in adult African elephant bulls in a shrub Mopane (Colophospermum
mopane) ecosystem was investigated. Large ulcers in the soles of at least one front foot were seen in
each of the recorded cases. Microscopically, the lesion can be described as a severe, chronic-active,
ulcerative, bacterial pododermatitis (complicated by hypersensitivity/septic vasculitis). A variety of bacteria
were isolated from these lesions as well as from regional lymph nodes. Streptococcus agalactiae
was the most consistent isolate, while Dichelobacter nodosus, the only organism known to be involved
with foot disease in domestic ruminants, was isolated from two cases. Contributory factors such as body
mass, portal of entry and origin of potential pathogens may have predisposed to the development of
