  		Figure 2. Phylogenetic tree based on 16S rRNA gene sequence comparisons over 1237 aligned bases showing novel phylotypes within the phylum Bacteroidetes. Tree was constructed by the neighbor-joining method following distance analysis of aligned sequences and was rooted for Lewinella persica. Numbers represent bootstrap values for each branch based on data for 100 trees. Accession numbers for 16S rRNA sequences are given for each strain. Scale bar shows number of nucleotide substitutions per site.

  		Figure 3. Phylogenetic tree based on 16S rRNA gene sequence comparisons over 1131 aligned bases showing novel phylotypes within the phylum Firmicutes. Tree was constructed by the neighbor-joining method following distance analysis of aligned sequences and was rooted for Atopobium rimae. Numbers represent bootstrap values for each branch based on data for 100 trees. Accession numbers for 16S rRNA sequences are given for each strain. Scale bar shows number of nucleotide substitutions per site.
