This review on Brucella abortus in cattle covers the pathogenesis, the epidemiology and the diagnostics of brucellosis. Emphasis is given to the presence of latent infections in young stock. Calves infected by B. abortus in utero or after ingestion of infected milk may acquire a persistent infection. These animals might present a significant problem in brucellosis control and eradication schemes, since they are difficult to detect by the usual serological tests as they remain negative until near the first calving or abortion. The diagnostics must be improved: (new) tests need to be made more sensitive and herds and/or animals should be tested more frequently after introduction of cattle into a herd. Moreover more attention should be paid to cases of abortion. It is also suggested that if the slaughter of infected herds is limited to adult animals, the heifer calves could be a source of infection to the restocked herd.
这篇关于牛布鲁氏菌病的综述涵盖了布鲁氏菌病的发病机制、流行病学和诊断方法。重点关注幼畜中潜伏感染的存在情况。子宫内感染布鲁氏菌流产亚种或摄入受感染牛奶的犊牛可能会发生持续性感染。这些动物在布鲁氏菌病的控制和根除计划中可能会带来重大问题，因为它们很难通过常规血清学检测发现，直到首次产犊或流产前不久一直呈阴性。必须改进诊断方法：（新的）检测需要提高敏感性，在牛引入牛群后，应对牛群和/或动物进行更频繁的检测。此外，应更加关注流产病例。还建议，如果将感染牛群的屠宰限制在成年动物，小母牛犊可能会成为重新补栏牛群的感染源。
