背景本研究旨在确定爱尔兰绵羊肝片吸虫的全国流行率，并根据参与羊群的管理和治疗实践进行风险分析评估。此外，与瘤胃吸虫的共感染进行了量化，并评估其与肝吸虫和管理措施的关联。方法选择305个羊群，确保羊群的全国代表性。参与的农场被要求在2014-2015年冬季完成一份关于农场管理做法的调查问卷，并提交粪便样本。分析合并粪便样本中是否存在F。肝吸虫和与瘤胃吸虫共感染。计算了瘤胃吸虫的表观患病率和真实患病率，并计算了与瘤胃吸虫的混合感染率。相关和回归分析用于评估管理措施，肝吸虫感染和合并感染与瘤胃吸虫之间的关联。结果全国F.肝硬化305例，占50.4%。地区流行率从东部的41%到南部的52%不等。在40%的研究群体中观察到与瘤吸虫的共感染，并且与增加的F。肝虫卵计数（OR = 2.9; P
Background The present study aimed to identify the national prevalence of Fasciola hepatica in Irish sheep and to conduct a risk analysis assessment based on management and treatment practices in participating flocks. Also, co-infection with rumen fluke was quantified and its association with liver fluke and management practices was assessed. Methods A total of 305 sheep flocks were selected ensuring even national representation of the sheep population. Participating farms were asked to complete a survey questionnaire on farm management practices and submit faecal samples during the winter of 2014-2015. Pooled faecal samples were analysed for the presence of F. hepatica and co-infection with rumen fluke. Apparent and true prevalence were calculated, additionally, the rate of co-infection with rumen fluke was also obtained. Correlation and regression analyses were used for assessing associations between management practices, liver fluke infection and co-infection with rumen fluke. Results The national true prevalence of F. hepatica was 50.4% (n = 305). Regional prevalence varied from 41% in the east to 52% in the south. Co-infection with rumen fluke was observed in 40% of the studied population and correlated with increased F. hepatica egg counts (OR = 2.9; P
