自 2011 年底发现以来，施马伦贝格病毒 (SBV) 在欧洲迅速传播。使用 2011 年 10 月至 2013 年 6 月期间收集的国内反刍动物的存档样本，通过血清中和试验估计了英国 (UK) 和爱尔兰共和国 (IE) 的血清阳性率。绵羊和牛之间的血清阳性率没有显着差异（P>0.05），这表明这两个物种在英国感染 SBV 的风险均没有显着增加。 2011 年的一个样本检测呈阳性；该样本于 11 月从威尔特郡的一头奶牛身上采集。 2012 年前三个季度，总体血清流行率稳步上升，然后在第四季度（10 月至 12 月）增加了一倍多，这可能反映了媒介活动的高峰。截至 2013 年 6 月，总体血清阳性率约为 72%。然而，尽管威尔士以及英格兰南部和中部县的血清阳性率超过 50%，但在英国和英格兰其他地区，血清阳性率却低于 50%。这表明2013年下半年仍有大量动物面临感染风险。(C) 2015 Elsevier B.V. 保留所有权利。
Since its identification in late 2011, Schmallenberg virus (SBV) spread rapidly across Europe. Using archived samples from domestic ruminants collected between October 2011 and June 2013, the seroprevalence in the United Kingdom (UK) and Republic of Ireland (IE) was estimated using a serum neutralisation test. There was no significant difference (P>0.05) in seroprevalence between sheep and cows suggesting that neither species is significantly more at risk of SBV infection in the UK. A single 2011 sample tested positive; the sample was taken in November from a cow in Wiltshire. There was a steady increase in overall seroprevalence during the first three quarters of 2012, which then more than doubled in quarter 4 (October-December), which may reflect a peak of vector activity. By the end of June 2013, overall seroprevalence was around 72%. However, although seroprevalence was over 50% in Wales and southern and central counties of England, it was below 50% in all other areas of the UK and IE. This suggests that there were still substantial numbers of animals at risk of infection in the latter half of 2013. (C) 2015 Elsevier B.V. All rights reserved.
