Abstract:
Since the original description of Borrelia bavariensis sp. nov. in 2009, additional samples available from humans and ticks from Europe and Mongolia, respectively, have been used to further characterize Borrelia strains belonging to this group of spirochaetes that utilize rodents as reservoir hosts. These investigations suggested the presence of related strains in Europe and Asia and confirmed their status as representing a distinct species. Furthermore, samples that were investigated by researchers from China and Japan confirm the ecological relationship of members of this proposed species with rodents and suggest that it has a wide distribution in Eurasia. Here, we use phylogenetic and genetic distance analyses to validate B. bavariensis sp. nov. as a species within the Borrelia burgdorferi sensu lato species complex. The type strain is PBi(T) ( = DSM 23469(T) = BAA-2496(T)).
