Sheep (3918) from 137 farms in the regions of North-, West- and Mid-Netherlands and Gelderland were serologically investigated for the presence of antibodies against Leptospira hardjo. Antibodies were detected in 3.3% of the sheep. There were large regional differences with respect to both the percentage of positive sheep and the percentage of positive flocks. All sera from sheep in Gelderland were negative. In West- en Mid-Netherlands there were 0.9 and 6.5% positive sera, respectively, and 19.4 and 32.7% positive flocks. The percentage of positive sheep per positive flocks varied from 1 tot 51.6. Serological positive sheep were from farms with and without cattle. On farms with cattle, there was no clear relationship between serologically sheep and the presence of hardjo antibodies in cattle. It thus seems plausible that sheep can be infected with hardjo independently of cattle.
对荷兰北部、西部、中部以及海尔德兰省137个农场的3918只绵羊进行了血清学调查，以检测抗哈氏钩端螺旋体抗体的存在情况。在3.3%的绵羊中检测到了抗体。在阳性绵羊百分比和阳性羊群百分比方面存在很大的地区差异。海尔德兰省所有绵羊的血清均为阴性。在荷兰西部和中部，阳性血清分别为0.9%和6.5%，阳性羊群分别为19.4%和32.7%。每个阳性羊群中阳性绵羊的百分比从1%到51.6%不等。血清学阳性的绵羊来自有牛和没有牛的农场。在有牛的农场，血清学阳性绵羊与牛体内哈氏钩端螺旋体抗体的存在之间没有明确的关系。因此，绵羊似乎有可能独立于牛感染哈氏钩端螺旋体。
