This study was carried out to determine the prevalence of rumen flukes on German cattle farms via the sedimentation technique, and to identify the rumen fluke species occurring in Germany. Additionally, the prevalence of patent infections was determined. Furthermore, a short questionnaire was answered by the farmers. A prevalence of 5.5% and 9.5% was detected for rumen flukes and liver flukes, respectively. Coinfections occurred on 2.1% of farms. In northern Germany, the rumen fluke prevalence was higher than in southern Germany, while for liver fluke the distribution was reversed. Rumen flukes were mostly identified as , but in four cases, sequencing revealed for the first time in Germany. Grazing and feeding of fresh grass, as well as organic farming, were significantly associated with rumen and liver fluke occurrence. In contrast, suckler cow husbandry only had an influence on the occurrence of rumen flukes, but not liver flukes. Trematode eggs could be detected in both, farms with and without deworming. Since there were only a few studies about Paramphistomidosis in Germany, more attention should be paid to these parasitic diseases for animal welfare and animal health reasons.
本研究旨在通过沉淀技术确定德国养牛场瘤胃吸虫的流行情况，并鉴定德国出现的瘤胃吸虫种类。此外，还确定了显性感染的流行情况。此外，养殖户还回答了一份简短的问卷。瘤胃吸虫和肝吸虫的检出率分别为5.5%和9.5%。2.1%的农场发生了混合感染。在德国北部，瘤胃吸虫的流行率高于德国南部，而肝吸虫的分布情况则相反。瘤胃吸虫大多被鉴定为 ，但在4例病例中，测序首次在德国发现了 。放牧和饲喂鲜草以及有机养殖与瘤胃吸虫和肝吸虫的发生显著相关。相比之下，奶牛养殖仅对瘤胃吸虫的发生有影响，对肝吸虫则无影响。在有驱虫和无驱虫的农场中均能检测到吸虫卵。由于德国关于双口吸虫病的研究较少，出于动物福利和动物健康的原因，应更多关注这些寄生虫病。
