宿主群落物种组成的变化可以改变疾病传播的风险。特别是，引入新的宿主物种会增加新的宿主和/或扩大外来或本地病原体的循环，从而增加健康威胁。莱姆病是一种多宿主媒介传播的疾病，由属于广义伯氏疏螺旋体复合体的细菌引起。它通过硬蜱的叮咬传播，特别是欧洲的硬蜱。以前的研究表明，西伯利亚花栗鼠，Tamias sibiricus barberi，一种引入法国巴黎附近的塞纳特森林的地松鼠，受到I.蓖麻，并因此感染了B。布格多费里湾一个指数的贡献，金花鼠的密度感染questing害虫的植被（即，对人类的蜱螨学风险）与两种已知的本地和同域的有能力储存宿主-河岸田鼠（Myodes glareolus）和林鼠（Apodemus sylvaticus）的风险进行了比较。花栗鼠产生的受感染的寻物数量是田鼠和小鼠的近8.5倍。此外，它们有助于B的更高多样性。burgdorferi sl基因种（B. Afzelii，B.严格意义上的burgdorferi和B. garinii）。根据蜱虫的可用性，花栗鼠的贡献在不同的年份和季节之间变化。作为T. S. barberi必须是一个合格的水库，它应该放大B。莱姆病螺旋体感染，因此增加了人类中莱姆病螺旋体病的风险。
The variation of the composition in species of host communities can modify the risk of disease transmission. In particular, the introduction of a new host species can increase health threats by adding a new reservoir and/or by amplifying the circulation of either exotic or native pathogens. Lyme borreliosis is a multi-host vector-borne disease caused by bacteria belonging to the Borrelia burgdorferi sensu lato complex. It is transmitted by the bite of hard ticks, especially Ixodes ricinus in Europe. Previous studies showed that the Siberian chipmunk, Tamias sibiricus barberi, an introduced ground squirrel in the Forest of Sénart (near Paris, France) was highly infested by I. ricinus, and consequently infected by B. burgdorferi sl. An index of the contribution of chipmunks to the density of infected questing nymphs on the vegetation (i.e., the acarological risk for humans) was compared to that of bank voles (Myodes glareolus) and of wood mice (Apodemus sylvaticus), two known native and sympatric competent reservoir hosts. Chipmunks produced nearly 8.5 times more infected questing nymphs than voles and mice. Furthermore, they contribute to a higher diversity of B. burgdorferi sl genospecies (B. afzelii, B. burgdorferi sensu stricto and B. garinii). The contribution of chipmunks varied between years and seasons, according to tick availability. As T. s. barberi must be a competent reservoir, it should amplify B. burgdorferi sl infection, hence increasing the risk of Lyme borreliosis in humans.
