Paramphistomidosis has recently been identified as an emerging parasitosis in Europe. This study estimated the prevalence of rumen flukes, and , in small ruminants in Germany and identified occurring rumen fluke species and potential predictors for fluke infections. Pooled fecal samples from 223 sheep farms and 143 goat farms in northern and southern Germany were examined by the sedimentation technique, and molecular species identification was performed on rumen-fluke-positive samples. In sheep, a flock prevalence of 2.2% was detected for rumen flukes. was identified on four of five positive farms, while species identification failed in one flock. No rumen fluke eggs were detected in the examined goat herds. eggs were detected in 2.7% of the sheep flocks, while the herd prevalence was 5.6% in goats. Higher prevalence values of 21.1% (sheep) and 7.0% (goats) were observed for . Mixed grazing with other ruminants and previously identified infections with rumen flukes and/or were identified as predictors for paramphistomidosis. The distribution of the three trematode species followed a geographical pattern associated with conditions favoring the relevant intermediate hosts. is an established parasite in German sheep at a currently low prevalence.
前后盘吸虫病最近被确定为欧洲一种新出现的寄生虫病。本研究估计了德国小型反刍动物瘤胃吸虫的流行率，并确定了出现的瘤胃吸虫种类以及吸虫感染的潜在预测因素。采用沉淀技术对德国北部和南部223个养羊场和143个养山羊场的粪便混合样本进行检测，并对瘤胃吸虫阳性样本进行分子物种鉴定。在绵羊中，瘤胃吸虫的群体流行率为2.2%。在五个阳性农场中的四个农场检测到了[未提及具体吸虫名称]，而在一个羊群中物种鉴定失败。在所检测的山羊群中未检测到瘤胃吸虫卵。在2.7%的绵羊群中检测到了[未提及具体吸虫名称]卵，而山羊群的群体流行率为5.6%。观察到[未提及具体吸虫名称]的流行率较高，绵羊为21.1%，山羊为7.0%。与其他反刍动物混牧以及先前确定的瘤胃吸虫和/或[未提及具体吸虫名称]感染被确定为前后盘吸虫病的预测因素。三种吸虫的分布遵循与有利于相关中间宿主的条件相关的地理模式。[未提及具体吸虫名称]是德国绵羊中一种已确定的寄生虫，目前流行率较低。
