牛是暂时命名为D型流感病毒的主要宿主，这种病毒可能与牛呼吸道疾病有关。在这里，我们使用2010-2016年间从日本不同地区几个看似健康的牛群收集的存档牛血清样本，对日本的D型流感病毒进行了血清学调查。我们在所有受检地区和所有年份都发现了血清阳性牛，总阳性率为30.5%，尽管不同地区的阳性率有所不同(13.5-50.0%)。荷斯坦黑牛和日本黑牛的阳性率没有显著差异。随着牛龄的增加，阳性率呈上升趋势。这些牛群被明确地分为两组：高阳性率和低(或无)阳性率，这表明病毒在牛群中很容易水平传播。这些数据表明，牛D流感病毒已经在全国范围内传播了至少5年，强调了它在日本牛种群中的普遍分布。
Cattle are major reservoirs of the provisionally named influenza D virus, which is potentially involved in the bovine respiratory disease complex. Here, we conducted a serological survey for the influenza D virus in Japan, using archived bovine serum samples collected during 2010–2016 from several herds of apparently healthy cattle in various regions of the country. We found sero-positive cattle across all years and in all the prefectural regions tested, with a total positivity rate of 30.5%, although the positivity rates varied among regions (13.5–50.0%). There was no significant difference in positivity rates for Holstein and Japanese Black cattle. Positivity rates tended to increase with cattle age. The herds were clearly divided into two groups: those with a high positive rate and those with a low (or no) positive rate, indicating that horizontal transmission of the virus occurs readily within a herd. These data demonstrate that bovine influenza D viruses have been in circulation for at least 5 years countrywide, emphasizing its ubiquitous distribution in the cattle population of Japan.
