Infectious causes of reproductive failure in cattle are important in Australia and New Zealand, where strict biosecurity protocols are in place to prevent the introduction and spread of new diseases. ranks highly as an important cause of reproductive wastage along with fungal and bacterial infections. , a leading cause of abortion elsewhere in the world, is foreign, following successful programs to control and eradicate the disease. Leptospirosis in cattle is largely controlled by vaccination, while and infections occur at low rates. In both countries, Bovine Viral Diarrhea virus (BVDV) infection rates as the second most economically important disease of cattle and one that also has an effect on reproduction. Effective disease control strategies require rapid diagnoses at diagnostic laboratories. To facilitate this process, this review will discuss the infectious causes of reproductive losses present in both countries, their clinical presentation and an effective pathway to a diagnosis.
在澳大利亚和新西兰，牛繁殖失败的传染性病因很重要，这两个国家都制定了严格的生物安全协议以防止新疾病的传入和传播。与真菌和细菌感染一样，[具体病因未提及]是繁殖浪费的重要原因。[具体病因未提及]在世界其他地方是导致流产的主要原因，但在成功实施控制和根除该疾病的计划后，在这两个国家已属外来病因。牛钩端螺旋体病主要通过疫苗接种来控制，而[具体病因未提及]和[具体病因未提及]感染发生率较低。在这两个国家，牛病毒性腹泻病毒（BVDV）感染率是牛的第二大经济重要性疾病，并且对繁殖也有影响。有效的疾病控制策略需要诊断实验室进行快速诊断。为促进这一过程，本综述将讨论这两个国家存在的繁殖损失的传染性病因、它们的临床表现以及有效的诊断途径。
