Phylogenetic trees of the entire borrelia lineage and ST633/ST680 based on the core chromosomal gene. A Based on the sequences of 567 core chromosomal genes of the entire borrelia lineage, a maximum-likelihood (ML) phylogenetic tree was constructed using RAxML with 1000 bootstrap replicates. Only bootstrap values over 60% are indicated. The bacteria transmitted by hard ticks, soft ticks, and lice are indicated in red, blue, and black, respectively. The sequence accession number and ST of each HTRF borreliae strain are shown in parentheses. The ST633 branch includes 21 sequences (10 Hokkaido isolates, 3 Mongolian isolates, and 8 Russian isolates). Sequences obtained in this study are indicated in bold. The scale bar indicates 5% sequence divergence. B An unrooted ML tree based on the sequences of 567 core chromosomal genes of 21 ST633 and 2 ST680 strains. Ten ST633 Hokkaido isolates, 8 ST633 Russian isolates, 3 ST633 Mongolian isolates, and 2 ST680 strains (both isolated in Honshu, Japan) are indicated in blue, green, red and yellow, respectively. The scale bar indicates 0.005% divergence
