The occurrence of the fox tapeworm Echinococcus multilocularis in Red foxes was studied in Belgium and a neighbouring region in The Netherlands. A total number of 1202 foxes were analysed (1018 in Belgium and 184 in The Netherlands) of which 179 were infected with E. multilocularis (164 in Belgium and 15 in The Netherlands). Further, the spatial distribution of infection among sampled foxes was analysed with an ellipsoidal gradient, demonstrating a decreasing prevalence in northwestern direction. Using this gradient, we showed that the spatial patterns of infection in Belgium and the neighbouring region in The Netherlands correspond, indicating a continuous distribution of E. multilocularis across the nation borders. Part of the Belgian data allowed investigating temporal changes in the spatial distribution of E. multilocularis. This revealed a northwestern spread of E. multilocularis.
在比利时和荷兰的一个邻近地区，对赤狐体内多房棘球绦虫（fox tapeworm Echinococcus multilocularis）的感染情况进行了研究。共分析了1202只狐狸（比利时1018只，荷兰184只），其中179只感染了多房棘球绦虫（比利时164只，荷兰15只）。此外，利用椭圆梯度分析了采样狐狸中感染的空间分布，结果表明感染率在西北方向呈下降趋势。利用这一梯度，我们发现比利时和荷兰邻近地区的感染空间模式是对应的，这表明多房棘球绦虫在国界两侧呈连续分布。部分比利时数据可用于研究多房棘球绦虫空间分布的时间变化。这揭示了多房棘球绦虫向西北方向扩散。
