Prevalence of anti-Neospora caninum antibodies was determined in sera of 320 dogs from Argentina using the indirect fluorescent antibody test (IFAT). Antibodies to N. caninum were found in 121 of 320 (37.8%) sera with titers of 1:50 (21 dogs), 1:100 (23 dogs), 1:200 (23 dogs), 1:400 (17 dogs), 1:800 (23 dogs), and > or = 1:1.600 (14 dogs). The seropositivity (IFAT, > or = 1:50) was higher in dogs from dairy (48% of 125) and beef (54.2% of 35) farms than in dogs from urban areas (26.2% of 160). Prevalence of anti-N. caninum antibodies was higher in dogs more than 12 mo of age (47.7%, 105 of 222) versus in 12-mo-old or younger dogs (12.7% of 86), suggesting postnatal exposure of N. caninum infection in dogs.
采用间接荧光抗体试验（IFAT）测定了来自阿根廷的320只犬血清中抗犬新孢子虫抗体的流行情况。在320份血清中的121份（37.8%）检测到了抗犬新孢子虫抗体，其滴度分别为1:50（21只犬）、1:100（23只犬）、1:200（23只犬）、1:400（17只犬）、1:800（23只犬）和≥1:1600（14只犬）。来自奶牛场（125只中的48%）和肉牛场（35只中的54.2%）的犬血清阳性率（IFAT，≥1:50）高于城市地区的犬（160只中的26.2%）。年龄超过12个月的犬抗犬新孢子虫抗体流行率（47.7%，222只中的105只）高于12个月龄及以下的犬（86只中的12.7%），这表明犬在出生后有犬新孢子虫感染暴露情况。
