Eurytrema sp. egg counts (epg) in the feces of naturally infected cattle were performed and the technique employed showed 94.2% probability of detecting positive cases of the infection with a single examination independently of the host parasite burden. It was also demonstrated that the epg of Eurytrema sp. follows a negative binomial distribution model and is characterized by its small magnitude.
对自然感染牛粪便中的阔盘吸虫虫卵计数（每克粪便虫卵数，epg），所采用的技术显示，单次检查检测到感染阳性病例的概率为94.2%，与宿主寄生虫负荷无关。还证明了阔盘吸虫的每克粪便虫卵数遵循负二项分布模型，且其数量较少。
