Ten unmedicated animals of a controlled anthelmintic trial were used to analyse the present gastrointestinal helminth fauna of young cattle from the northwest of Germany. This survey done in August revealed Ostertagia ostertagi to represent the most prevalent and abundant species followed by Cooperia oncophora and Nematodirus helvetianus. O. lyrata, O. leptospicularis, C. zurnabada, C. punctata, Trichostrongylus axei, Haemonchus contortus, Bunostomum phlebotomum, Capillaria bovis and Trichuris discolor were less prevalent and abundant. These findings are closely similar to findings from investigations more than 20 years ago although since that time anthelmintics have been used increasingly.
一项对照驱虫试验中选用了10只未用药的动物，以分析德国西北部幼牛目前的胃肠道蠕虫区系。8月份进行的这项调查显示，奥斯特他线虫是最常见且数量最多的物种，其次是牛库珀线虫和瑞士细颈线虫。叶氏奥斯特他线虫、细尖奥斯特他线虫、祖氏库珀线虫、点状库珀线虫、斧形毛圆线虫、捻转血矛线虫、牛钩口线虫、牛毛细线虫和变色毛首线虫的流行率和数量较少。这些发现与20多年前的调查结果非常相似，尽管自那时以来驱虫药的使用越来越多。
