Introduced Siberian chipmunks (Tamias sibiricus barberi) harbour more diverse Borrelia burgdorferi sensu lato genospecies than native bank voles (Myodes glareolus).

In this study, we investigated whether an introduced species, the Siberian chipmunk (Tamias sibiricus barberi), was a potentially new reservoir host for Borrelia burgdorferi sensu lato (sl), causative agents of Lyme disease. First, we ascertained whether chipmunks were infected by all of the B. burgdorferi sl genospecies associated with rodents and available in their source of infection, questing nymphs. Second, we determined whether the prevalence and diversity of B. burgdorferi sl in chipmunks was similar to that of a native reservoir rodent, the bank vole (Myodes glareolus). Our research took place between 2006 and 2008 in a suburban French forest, where we trapped 335 chipmunks and 671 voles, and collected 743 nymphs of ticks that are questing for hosts by dragging on the vegetation.
