一个地区的病媒传播疾病生态可归因于病媒-宿主相互作用。在美国，蜱传病原体是报告的病媒传播疾病数量最多的原因。在美国东部大西洋中部地区，蜱传疾病（如莱姆病）的发病率有所增加，蜱-宿主-病原体相互作用被认为是导致发病率增加的一个因素。蜱虫在从全身感染宿主处吸食血液后感染病原体，或在与其他感染蜱虫共同取食宿主时通过局部感染感染。宿主不仅在蜱虫获得病原体方面发挥作用，而且还可以促进蜱虫在一个区域内的局部扩散或在更远的距离内扩散到其历史分布范围之外的新地理范围。在弗吉尼亚州东南部（美国）进行的这项研究中，我们检查了留鸟和候鸟物种与硬蜱（狭义伯氏疏螺旋体的主要载体）之间的相互作用。美国东海岸莱姆病的主要病原体。在两年期间（2012-2014年），调查了1879只雀形目鸟类，并对255只硬蜱进行了疏螺旋体属的存在测试。代表17种鸟类的80只雀形目鸟类（4.3%）被至少一种硬蜱寄生，但只有3种鸟类被检测为B阳性的硬蜱寄生。狭义伯氏疏20只硬蜱（7.8%）检测为B阳性。狭义伯氏疏几乎所有的都是从留鸟物种收集的，包括卡罗莱纳鹪鹩（Thryothorus ludovicianus）和棕色矢鸫（Toxostoma rufum）。鉴于数百万只鸟类在迁徙过程中经过弗吉尼亚州东南部，即使寄生在雀形目鸟类身上的硬蜱数量很少，B的流行率也很低。狭义伯氏疏在收集的硬蜱中发现，雀形目鸟类的绝对数量表明它们可能在B的维持和传播中发挥作用。狭义伯氏疏在弗吉尼亚州东南部。
The ecology of vector-borne diseases in a region can be attributed to vector-host interactions. In the United States, tick-borne pathogens are the cause of the highest number of reported vector-borne diseases. In the mid-Atlantic region of the eastern United States, tick-borne diseases such as Lyme disease, have increased in incidence, with tick-host-pathogen interactions considered a contributing factor to this increase. Ticks become infected with pathogens after taking a blood meal from a systemically infected host or through a localized infection while co-feeding on a host with other infected ticks. The host not only plays a role in pathogen acquisition by the tick, but can also facilitate dispersal of the tick locally within a region or over greater distances into new geographical ranges outside of their historical distributional range. In this study conducted in southeastern Virginia (USA), we examined the interaction between both resident and migratory bird species and Ixodes ticks, the primary vectors of Borrelia burgdorferi sensu stricto (s.s.) the main causative agent of Lyme disease on the East coast of the United States. Over a two-year period (2012–2014), 1879 passerine birds were surveyed, and 255 Ixodes ticks tested for the presence of Borrelia spp. Eighty passerine birds (4.3%) representing 17 bird species were parasitized by at least one Ixodes tick, but only three bird species were parasitized by Ixodes ticks that tested positive for B. burgdorferi s.s. Twenty Ixodes ticks (7.8%) tested positive for B. burgdorferi s.s. with nearly all collected from resident bird species including the Carolina wren (Thryothorus ludovicianus) and brown thrasher (Toxostoma rufum). Given that millions of birds pass through southeastern Virginia during migration, even with the low number of Ixodes ticks parasitizing passerine birds and the low prevalence of B. burgdorferi s.s. found within Ixodes ticks collected, the sheer volume of passerine birds suggests they may play a role in the maintenance and dispersal of B. burgdorferi s.s. in southeastern Virginia.
