Five kudus (Tragelaphus strepsiceros), three bulls and two cows, within the Greater Kruger National Park complex, were diagnosed with generalized tuberculosis caused by Mycobacterium bovis. The lesions seen in these animals were similar to those previously reported in kudus and included severe tuberculous lymphadenitis of the nodes of the head and neck (that resulted in noticeable uni- or bilateral swelling beneath the ear), thorax, and the mesentery. All the animals also suffered from severe granulomatous pneumonia. The lesions in the lungs were more severe cranially and had a miliary distribution elsewhere in the lungs. Based on the DNA patterns of the M. bovis isolates, at least some of these kudus were infected with strains commonly present in tuberculous buffaloes, lions, cheetahs, and baboons in the Park whereas other strains from these kudus were quite different and may reflect another source of infection. The presence of tuberculous kudus in the Park is expected to complicate control measures that may be instituted to contain or eradicate the disease in the Park.
在大林波波跨国公园综合体范围内,五只捻角羚(南非大羚羊),三只雄性和两只雌性,被诊断出患有由牛分枝杆菌引起的全身性结核病。这些动物身上出现的病变与先前在捻角羚身上报道的病变相似,包括头颈部淋巴结严重的结核性淋巴结炎(导致耳朵下方明显的单侧或双侧肿胀)、胸部以及肠系膜。所有动物还患有严重的肉芽肿性肺炎。肺部病变在颅骨部位更严重,在肺部其他部位呈粟粒状分布。根据牛分枝杆菌分离株的DNA模式,这些捻角羚中至少有一些感染了公园内患结核病的水牛、狮子、猎豹和狒狒中常见的菌株,而来自这些捻角羚的其他菌株则有很大不同,可能反映了另一种感染源。公园内出现患结核病的捻角羚预计会使为控制或根除公园内该疾病而可能采取的控制措施变得复杂。
