Influenza D virus (IDV) is a new member of the Orthomyxoviridae family. It was first reported in swine in 2011 and isolated from bovine samples received for routine respiratory disease diagnosis in Ireland during 2014-2016. The goal of this study was to determine the seroprevalence in selected populations of IDV in cattle, pigs and sheep. Results showed a high prevalence of IDV in cattle sampled at slaughter (94.6%) or for diagnostic reasons (64.9%), whereas prevelance in samples taken for diagnostic reasons from sheep (4.5%) and pigs (5.8%) was much lower. This study suggests that IDV is widespread in Irish cattle.

在选定的爱尔兰牛，羊和猪样本组中，D型流感病毒的血清阳性率。

D型流感病毒（IDV）是正粘病毒科的新成员。它于2011年在猪中首次报道，并从2014-2016年间在爱尔兰进行常规呼吸系统疾病诊断的牛样品中分离得到。这项研究的目的是确定牛，猪和羊的特定IDV人群的血清阳性率。结果显示，在屠宰时（94.6％）或出于诊断原因（64.9％）的牛中，IDV的患病率很高，而出于诊断原因而从绵羊（4.5％）和猪（5.8％）中获取的样本中的流行率要低得多。这项研究表明，IDV在爱尔兰牛中很普遍。
