Between February 1990 and July 1991, 18 harbour porpoises (Phocoena phocoena) and 248 common guillemots (Uria aalge), found dead along the Belgian and German coasts, were examined for their burden of helminths. A total of three species were found in the guillemots (one cestode, one nematode and one pentastomid), and six species in the porpoises (one trematode, one cestode and four nematodes). Among the guillemots the burden of helminths was not statistically different between juvenile and adult birds. The deaths of the birds were apparently not related to the parasite infections. In contrast, the adult porpoises were more heavily parasitised than the juveniles, except for one young porpoise stranded on the Belgian coast. In the porpoises, four species of parasites had a pathological effect and Torynurus convolutus was responsible for the death of one animal from the Belgian coast and three from the German coast.
1990年2月至1991年7月期间，对在比利时和德国海岸发现死亡的18只港湾鼠海豚（Phocoena phocoena）和248只普通海鸠（Uria aalge）进行了寄生虫负荷检查。在海鸠中总共发现了三种寄生虫（一种绦虫、一种线虫和一种舌形虫），在鼠海豚中发现了六种（一种吸虫、一种绦虫和四种线虫）。在海鸠中，幼鸟和成鸟的寄生虫负荷在统计学上没有差异。鸟类的死亡显然与寄生虫感染无关。相比之下，成年鼠海豚比幼年鼠海豚的寄生虫感染更严重，但有一只搁浅在比利时海岸的幼年鼠海豚除外。在鼠海豚中，有四种寄生虫具有病理作用，旋扭线虫（Torynurus convolutus）导致了一只来自比利时海岸和三只来自德国海岸的鼠海豚死亡。
