This study was aimed at determining the prevalence of anti-Neospora caninum antibodies in serum samples from 667 goats, collected from 90 herds in 90 municipalities in eight of the twelve mesoregions of Minas Gerais State. The presence of anti-N. caninum antibodies was determined by IFAT with a cut-off value of 1:50. The true herd-level seroprevalence in the entire study area was 75.2% (CI 95%: 59.5-90.9%). The true individual-level seroprevalence in the entire study area was 10.7% (CI 95%: 8.3-13.4%) with titers ranging from 50 (50.5%) to 3200 (1.7%). The serological evidence from this study indicated that N. caninum infection is widely distributed among goat-rearing herds in Minas Gerais and further studies are needed in order to evaluate the impact of this parasite as a cause of reproductive disorders.
本研究旨在确定来自米纳斯吉拉斯州 12 个地区中 8 个地区的 90 个市的 90 个畜群中 667 只山羊血清样本中抗新孢子虫抗体的流行率。使用间接荧光抗体试验（IFAT）检测抗 N. caninum 抗体，截断值为 1:50。整个研究区域的真实畜群血清流行率为 75.2%（95%置信区间：59.5-90.9%）。整个研究区域的真实个体血清流行率为 10.7%（95%置信区间：8.3-13.4%），滴度范围从 50（50.5%）到 3200（1.7%）。本研究的血清学证据表明，新孢子虫感染在米纳斯吉拉斯州的山羊养殖畜群中广泛分布，需要进一步研究以评估该寄生虫作为生殖障碍原因的影响。
