This paper reports the first detection of Borrelia miyamotoi in UK Ixodes ricinus ticks. It also reports on the presence and infection rates of I. ricinus for a number of other tick-borne pathogens of public health importance. Ticks from seven regions in southern England were screened for B. miyamotoi, Borrelia burgdorferi sensu lato (s.l.), Anaplasma phagocytophilum and Neoehrlichia mikurensis using qPCR. A total of 954 I. ricinus ticks were tested, 40 were positive for B. burgdorferi s.l., 22 positive for A. phagocytophilum and three positive for B. miyamotoi, with no N. mikurensis detected. The three positive B. miyamotoi ticks came from three geographically distinct areas, suggesting a widespread distribution, and from two separate years, suggesting some degree of endemicity. Understanding the prevalence of Borrelia and other tick-borne pathogens in ticks is crucial for locating high-risk areas of disease transmission.
本文报道了在英国蓖麻硬蜱中首次检测到宫本疏螺旋体。它还报告了蓖麻硬蜱中一些其他具有公共卫生重要性的蜱传病原体的存在情况和感染率。使用定量聚合酶链反应（qPCR）对英格兰南部七个地区的蜱进行了宫本疏螺旋体、狭义伯氏疏螺旋体、嗜吞噬细胞无形体和米库雷新埃立克体的筛查。总共检测了954只蓖麻硬蜱，40只狭义伯氏疏螺旋体呈阳性，22只嗜吞噬细胞无形体呈阳性，3只宫本疏螺旋体呈阳性，未检测到米库雷新埃立克体。三只宫本疏螺旋体呈阳性的蜱来自三个地理上不同的区域，表明分布广泛，且来自两个不同年份，表明存在一定程度的地方性流行。了解蜱中疏螺旋体和其他蜱传病原体的流行情况对于确定疾病传播的高风险区域至关重要。
