a Phylogenetic tree of Borrelia species based on the concatenated alignment of nucleotide sequences of 249 core genes located on the chromosome. Borrelia miyamotoi clusters with relapsing fever species. b Phylogenetic tree of B miyamotoi strains based on concatenated alignment of nucleotide sequences of 719 core genes. A maximum likelihood tree was constructed using RAxML software using a nucleotide substitution model with a gamma distribution of variable positions (GTR + Γ). The resulting tree was midpoint rooted using Figtree (http://tree.bio.ed.ac.uk/software/figtree/). Long branches shown not according to scale are indicated by dashed lines. Scale bar indicates substitution rates
