Prediction of novel reservoirs of zoonotic pathogens would be improved by the identification of interspecific drivers of host competence (i.e., the ability to transmit pathogens to new hosts or vectors). Tick‐borne pathogens can provide a useful model system, because larvae become infected only when feeding on a competent host during their first blood meal. For tick‐borne diseases, competence has been studied best for Borrelia burgdorferi sensu lato (Bbsl), which causes Lyme borreliosis. Major reservoirs include several small mammal species, but birds might play an under‐recognized role in human risk given their ability to disperse infected ticks across large spatial scales. Here, we provide a global synthesis of the ecological and evolutionary factors that determine the ability of bird species to infect larval ticks with Bbsl.

伯氏疏螺旋体的鸟类能力的宏观生态学和进化

通过鉴定宿主能力的种间驱动因素(即,将病原体传播到新宿主或载体的能力),可以改善人畜共患病原体新储库的预测。ick传播的病原体可以提供一个有用的模型系统,因为幼虫只有在其第一次血餐中以合格的宿主为食时才被感染。对于壁虱传播的疾病,对博氏疏螺旋体Borrelia burgdorferi sensu lato)(Bbsl),会导致莱姆病。主要的水库包括几种小型哺乳动物,但是鉴于鸟类能够在较大的空间尺度上分散受感染的tick,因此它们在人类风险中的作用可能未被充分认识。在这里,我们提供了生态和进化因素的全球综合信息,这些因素决定了鸟类感染Bb sl幼虫的能力。
