Molecular phylogenetic analysis of flaB gene fragment (605 bp) of Borrelia burgdorferi s.l. The evolutionary history was inferred by using the Maximum Likelihood method and Tamura 3-parameter model. The tree with the highest log likelihood (−1385.02) is shown. The percentage of trees in which the associated taxa clustered together is shown next to the branches. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. This analysis involved 23 nucleotide sequences. There was a total of 476 positions in the final dataset.
