红松鼠（学名：Sciurus vulgaris）原产于欧亚大陆的大部分地区;在英国的大部分地区，它们已经被非本土的灰松鼠所取代，并被认为是濒危物种。关于英国红松鼠接触的蜱传病原体的范围知之甚少。作为捕获和释放调查的一部分，检查分枝杆菌属的患病率。在两个英国岛屿的红松鼠种群中，从松鼠中除去蓖麻硬蜱并PCR筛选疏螺旋体属，细胞内节肢动物携带的细菌和寄生蜂Ixodiphagus hookeri。在这两个研究中心，最常见的蜱传播细菌是广义伯氏疏螺旋体（总体最低患病率12.7%），其次是嗜吞噬细胞无形体（总体最低患病率1.6%）。在两个研究中心均发现感染螺原体的单蜱，在一个研究中心发现感染宫本疏螺旋体或埃立克体属的单蜱。携带沃尔巴克氏体的蜱（总体最低患病率15.2%）均为I阳性。hookeri。我们的研究表明，英国红松鼠可能通过喂养蜱虫暴露于各种细菌病原体。对这种已经脆弱的野生动物物种的健康和生存的影响尚不清楚，需要进一步研究来评估疏螺旋体和其他蜱传病原体对红松鼠构成的威胁。
Red squirrels (Sciurus vulgaris) are native to most of Eurasia; in much of the United Kingdom, they have been supplanted by the non-native grey squirrel, and are considered an endangered species. Very little is known about the range of tick-borne pathogens to which UK red squirrels are exposed. As part of trap-and-release surveys examining prevalence of Mycobacterium spp. in red squirrel populations on two UK islands, Ixodes ricinus ticks were removed from squirrels and PCR screened for Borrelia spp., intracellular arthropod-borne bacteria and the parasitic wasp Ixodiphagus hookeri. At both sites, the most commonly encountered tick-transmitted bacterium was Borrelia burgdorferi sensu lato (overall minimum prevalence 12.7%), followed by Anaplasma phagocytophilum (overall minimum prevalence 1.6%). Single ticks infected with Spiroplasma were found at both sites, and single ticks infected with Borrelia miyamotoi or an Ehrlichia sp. at one site. Ticks harbouring Wolbachia (overall minimum prevalence 15.2%) were all positive for I. hookeri. Our study shows that UK red squirrels are potentially exposed to a variety of bacterial pathogens via feeding ticks. The effects on the health and survival of this already vulnerable wildlife species are unknown, and further studies are needed to evaluate the threat posed to red squirrels by Borrelia and other tick-borne pathogens.
