血清是从意大利西北部的 490 只狗身上采集的。城市有188只狗，农村有302只狗。其中牧羊犬190只，养牛场犬112只。使用新孢子虫凝集试验检测血清中是否存在抗犬新孢子虫抗体。农村犬在 1/40、1/80、1/160 稀释滴度下的血清阳性率（分别为 36.4%、19.5%、9.9%）显着高于城市犬（分别为 20.2%、10.6%、4.8%）。男性和女性的血清阳性率没有显着差异。在牧羊犬中，患病率随着狗的年龄而增加，因此表明产后通过水平传播接触。在农村狗中观察到的较高血清阳性率表明生活方式和饮食习惯（即流产的胎儿、胎盘和小型哺乳动物）在获得犬新孢子虫感染中的重要性。我们的结果证实，狗接触过犬新孢子虫，并在犬新孢子虫的流行病学中发挥着重要作用。
Sera were collected from 490 dogs from north-west Italy. One hundred and eighty-eight dogs were urban, while 302 dogs were rural. Among the latter, 190 were shepherd dogs and 112 were cattle farm dogs. Sera were tested for the presence of antibodies against Neospora caninum using the Neospora agglutination test. Seroprevalence at 1/40, 1/80, 1/160 dilution titres was significantly higher in rural (36.4%, 19.5%, 9.9% respectively) than in urban dogs (20.2%, 10.6%, 4.8% respectively). Seroprevalence did not differ significantly in males and females. In shepherd dogs, prevalence increased according to dogs' age, thus suggesting a post-natal exposure by horizontal transmission. The observed higher seroprevalence in rural dogs suggests the importance of lifestyle and alimentary habits (i.e. aborted foetuses, placentas and small mammals) in the acquisition of N. caninum infection. Our results confirm that dogs are exposed to N. caninum and play an important role in the epidemiology of N. caninum.
