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 the lesions.
对非洲成年雄性大象在灌木巴豆树（Colophospermum mopane）生态系统中严重跛行的情况进行了调查。在每个记录案例中，至少一只前脚的脚底出现了大溃疡。在显微镜下，病变可描述为严重的、慢性活动性、溃疡性细菌性足皮炎（并发超敏反应/感染性血管炎）。从这些病变以及局部淋巴结中分离出了多种细菌。无乳链球菌是最常见的分离菌，而结节类杆菌，这种在家养反刍动物中唯一已知与足部疾病有关的微生物，在两例中被分离出来。体重、潜在病原体的进入途径和来源等促成因素可能是导致病变发展的原因。
