This work estimates the economic losses due to Neospora abortions in the humid pampa region of Argentina.The total dairy and beef cattle population at risk of abortion is 1,771,326 and 9,726,684 head, respectively. In dairy cattle, there was an 8 % risk of experiencing abortion due to a variety of causes, but 16.5 % of them were due to Neospora caninum. The economic losses were estimated at US$1,415 (1,400-1,431) per abortion, which equates to a total loss of US$33,097,221 (15,622,600-119,349,693) for the dairy industry at the humid pampa region of Argentina. In beef cattle, the overall risk of abortion was estimated to be 4.5 % for all pregnancies,whereas 6.7 % are specifically due to N. caninum, with an economic loss of US$440 (range, 150-730) per abortion.This amounts to an annual loss to the beef industry of US$12,903,440 (range, 1,130,700-42,070,630) in the same area. The results of this study show that Neospora infections and thus abortions cause severe economic impacts in the dairy and beef industries in the humid pampa region of Argentina, which is one the most important areas of cattle production in the world [corrected].
这项研究估算了阿根廷湿润潘帕斯地区因新孢子虫病导致流产造成的经济损失。面临流产风险的奶牛和肉牛总数分别为1771326头和9726684头。在奶牛中，因各种原因流产的风险为8%，但其中16.5%是由犬新孢子虫引起的。据估计，每次流产造成的经济损失为1415美元（1400 - 1431美元），这相当于阿根廷湿润潘帕斯地区奶牛业的总损失为33097221美元（15622600 - 119349693美元）。在肉牛中，所有怀孕母牛的总体流产风险估计为4.5%，而因犬新孢子虫导致的流产占6.7%，每次流产造成的经济损失为440美元（范围为150 - 730美元）。这相当于同一地区肉牛业每年损失12903440美元（范围为1130700 - 42070630美元）。这项研究结果表明，新孢子虫感染进而导致的流产给阿根廷湿润潘帕斯地区的奶牛业和肉牛业造成了严重经济影响，该地区是世界上最重要的养牛区之一[已修正]。
