In a population-based study with 4 years of follow up, we evaluated the prevalence of Coxiella burnetii in cattle on Ulleung Island, Korea. In this study, the rates of C. burnetii infection in cattle on Ulleung Island were determined by PCR and were found to be 0.3-1.0% in the period 2011-2014. All 17 C. burnetii partial 16S rRNA gene sequences from PCR-positive cattle were identical and 2 geographic representatives were included in our analysis. The nucleotide sequences of the 2 samples showed high (98.4-100%) identity with C. burnetii sequences obtained from the GenBank. In this long-term tracking study, the number of cattle positive for C. burnetii on Ulleung Island was low. To prevent the transmission of C. burnetii on Ulleung Island, control strategy should include biosecurity improvement in surveillance, livestock management, administering suitable tests before purchasing animals to detect C. burnetii shedders, and restricting movements between herds.
在一项为期4年随访的基于人群的研究中，我们评估了韩国郁陵岛牛群中伯氏考克斯体的流行情况。在本研究中，通过聚合酶链反应（PCR）测定了郁陵岛牛群中伯氏考克斯体的感染率，发现在2011 - 2014年期间为0.3 - 1.0%。来自PCR阳性牛的所有17个伯氏考克斯体部分16S rRNA基因序列均相同，我们的分析纳入了2个地理代表性样本。这2个样本的核苷酸序列与从基因库获得的伯氏考克斯体序列显示出高度（98.4 - 100%）同源性。在这项长期跟踪研究中，郁陵岛伯氏考克斯体阳性牛数量较少。为防止郁陵岛伯氏考克斯体的传播，控制策略应包括在监测、家畜管理方面加强生物安全，在购买动物前进行适当检测以发现伯氏考克斯体排泄者，并限制畜群间的流动。
