Comparison of phylogenetic trees. a Our reconstruction of the phylogenetic tree of flaB nucleotide sequences from 8 Texas specimens, the B31 genome, and the variant B31 flaB X15661. The tree was prepared using sequences trimmed to equal length by removing the first 4 positions and the last 2 positions of the aligned sequences in Fig. 1. The tree is consistent with 100 % identity between 7 of 8 Texas specimens with the B31 sequence. MMWMA69-10 and B31_X15661 each have one nucleotide difference. b Fig. three-a in the Esteve-Gassent et al. response [4], in which reverse complement sequences for B. burgdorferi N40 and BWTX12-16, as well as sequence ends that were not trimmed to the same length, were apparently utilized. Note the difference in the scale bars
