FIG. 6.

Phylograms of ospE-related genes. Phylograms were constructed by using the translated amplicon sequences determined in this study and other, previously determined sequences as described in Materials and Methods. The isolate from which a particular amplicon was obtained is indicated at the terminus of the branch. The designations p21 (26), ospE (14), and erpA and erpC (25) indicate gene names, and these sequences were previously determined by others. The phylogram on the left was constructed by using the alignment presented in Fig. 4, while the phylogram on the right was constructed by using the same alignment after deletion of variable domains 1 and 2. Note that some clustering relationships changed as a result of deletion of the variable domains.
