FIG. 1.

Dendrogram of DNA sequences demonstrating the relatedness of representatives from the original pgf 54 group from B. burgdorferi B31 sensu stricto (Bb), B. garinii (Bg), and B. afzelii (Ba). Clustal V analysis was performed as described in Materials and Methods. Divergence values used to produce the dendrogram were calculated using Lasergene software and are presented in Table S1 in the supplemental material. The new paralogous family (gbb fam_b_burgdorferi_b31.pep_35) is indicated to the right. The dashed box highlights the clade composed of closely related BBA65 and BBA66 orthologs. The scale represents the percentage of nucleotide substitutions observed out of the total number of nucleotides compared.
