Amphistomiasis, a neglected trematode infection of ruminants, has recently come up as an important reason for economic losses. The aim of this study was to determine the prevalence of bovine amphistomiasis and associated risk factors such as: age, gender, breed, season, water source, pastureland and grazing system. Between January 2016 and 2017, a total of 1,000 faecal samples and 1,000 rumens of cattle were collected from slaughterhouse of Zabol, Iran ante-mortem and post-mortem, respectively, and examined. The overall prevalence was 34.6% and 19.5% in terms of amphistome adults and eggs respectively. The identified amphistome species and their prevalence were Paramphistomumcervi (13.3%), Cotylophoroncotylophorum (19.5%), Gastrothylaxcrumenifer (5.9%) and Carmyeriusspatiosus (2.7%). The correlation between prevalence and season, age, breed, water source, pastureland and grazing system was significant (p < .0001). The presented information about the prevalence of amphistomes of cattle and individual and management risk factors can be used to design appropriate control measures.
片形吸虫病是一种被忽视的反刍动物吸虫感染，最近成为经济损失的一个重要原因。本研究旨在确定牛片形吸虫病的流行情况以及相关的风险因素，如：年龄、性别、品种、季节、水源、牧场和放牧制度。2016 年 1 月至 2017 年期间，分别从伊朗扎布尔屠宰场的宰前和宰后采集了 1000 份粪便样本和 1000 份牛瘤胃液进行检查。成虫和虫卵的总流行率分别为 34.6%和 19.5%。鉴定出的片形吸虫种类及其流行率分别为：莫氏片形吸虫（13.3%）、双腔片形吸虫（19.5%）、胃双腔吸虫（5.9%）和腔阔盘吸虫（2.7%）。流行率与季节、年龄、品种、水源、牧场和放牧制度之间的相关性显著（p<.0001）。本研究提供了有关牛片形吸虫感染的流行情况以及个体和管理风险因素的信息，可用于设计适当的控制措施。
