The objective of this study was to describe the epidemiology of Toxoplasma gondii and Neospora caninum infection by estimating seroprevalence and its association with certain risk factors in goats from Aguascalientes, Mexico. A total of 150 blood samples was taken from 10 farms and serum samples were subjected to enzyme-linked immunosorbent assay indirect test to detect T. gondii and N. caninum antibodies; the association between seroprevalence and some potential risk factors was estimated through logistic regression analysis. The general seroprevalence for T. gondii was 12.6%, observed in the farms in a range of 6.6 to 60%, finding seropositive animals in 80% of them; for N. caninum the seroprevalence was 3.3% and in farms a range of 6.6 to 13.3% was identified and 30% of them had at least 1 seropositive animal. The coinfection was 0.66%. The risk analysis for T. gondii identified a history of abortions (odds ratio 9.25) as a factor associated with seroprevalence; for N. caninum, no risk factor was identified.

本研究的目的是通过估计墨西哥阿瓜斯卡连特斯山羊的血清流行率及其与某些危险因素的关系来描述弓形虫和犬新孢子虫感染的流行病学。共从10个养殖场抽取150份血液样本，对血清样本进行酶联免疫吸附法间接检测，检测弓形虫和犬新孢子虫抗体；通过逻辑回归分析估计血清流行率与一些潜在危险因素之间的关联。弓形虫的总体血清阳性率为 12.6%，农场中的血清阳性率为 6.6% 至 60%，其中 80% 的动物呈血清阳性；犬新孢子虫的血清阳性率为 3.3%，农场中的血清阳性率为 6.6% 至 13.3%，其中 30% 的农场至少有 1 只动物呈血清阳性。合并感染率为0.66%。弓形虫风险分析确定流产史（比值比 9.25）是与血清阳性率相关的一个因素；对于犬新孢子虫，没有发现危险因素。
