The seroprevalence of Neospora caninum infection was estimated from a sample of 813 cattle from 20 dairy herds in five regions in Mexico. The true prevalence of infection was estimated to be 42% (95% CI: 39, 46). Seropositivity was associated with abortion (odds ratio (OR)=2.0) and was higher among cows raised on-farm (41%), than among replacement cattle purchased outside the farm (28%). The ORs relating abortion to seropositivity in individual herds ranged from 1.3 to 10. Overall, 26% of the abortions were attributed to N. caninum.
从墨西哥五个地区20个奶牛场的813头牛的样本中估算了犬新孢子虫感染的血清流行率。估计感染的实际流行率为42%（95%置信区间：39, 46）。血清阳性与流产相关（优势比（OR）=2.0），并且在农场饲养的奶牛中（41%）血清阳性率高于从农场外购买的后备牛（28%）。各个牛群中流产与血清阳性的OR值范围为1.3至10。总体而言，26%的流产归因于犬新孢子虫。
