The base line prevalence of Echinococcus multilocularis in foxes was determined in the eastern part of the province of Groningen in the Netherlands adjacent to the German border. This region has been identified in a previous study in 1998 as one of the westernmost border areas of E. multilocularis. Base line prevalence data are important for a better insight in the possible spread of the parasite and its changes in time. As fox feces containing E. multilocularis eggs are an important source for human exposure this base line prevalence is also an indicator for the potential risk for public health. The base line prevalence was estimated at 9.4% (95% CI: 5.2-16.5%). These results confirm previous findings of E. multilocularis in the same region. The spatial distribution of the infected foxes has been analyzed as a spatial gradient using a logistic model. The prevalence appeared to change strongest in east-western direction and was highest near the German border, adjacent to a German endemic area. These results suggest that the border areas in the Netherlands are the most margin of E. multilocularis territory.
在荷兰格罗宁根省东部与德国接壤的地区，确定了多房棘球绦虫在狐狸中的基线流行率。该地区在1998年的一项先前研究中被确定为多房棘球绦虫最西部的边境地区之一。基线流行率数据对于更好地了解寄生虫的可能传播及其随时间的变化非常重要。由于含有多房棘球绦虫卵的狐狸粪便 是人类接触的重要来源，因此该基线流行率也是公共卫生潜在风险的指标。基线流行率估计为9.4%（95%置信区间：5.2 - 16.5%）。这些结果证实了之前在同一地区发现的多房棘球绦虫。使用逻辑模型将受感染狐狸的空间分布分析为空间梯度。流行率在东西方向变化最为明显，在靠近德国边境且与德国疫区相邻的地方最高。这些结果表明，荷兰的边境地区是多房棘球绦虫分布区域的最边缘地带。
