Maximum-likelihood phylogenetic tree of 16S rRNA genes for all Meganema isolates and closely related species in the LTP database (LTPs111) [ 10 ] constructed using the ARB software [ 13 ]. The 1342 bp long sequence fragment of the unique 16S rRNA gene copy in the genome is identical with the previously published 16S rRNA gene sequence for the Gr1T strain (AF18048). A 20% maximum frequency filter was applied in order to remove hypervariable positions. Included are all uncultured clone sequences from the NCBI database which share ≥94% sequence similarity with the Gr1T strain (all were ≥ 98%), with sequences from the same study clustered at ≥ 99% similarity and a representative included. Bootstrap values, calculated from 100 re-samplings, are indicated for branches with > 50% support. Scale bar represents substitutions per nucleotide. The family Fusobacteriaceae was used as the out-group.
