Maximum likelihood tree of 16S rRNA gene clone sequences recovered of the midgut of Cansiliella servadeii affiliated with Proteobacteria and Bacteriodetes. Sequences from GenBank dataset showing the closest similarity levels have been added. The percentages of replicate trees in which the associated taxa clustered together in the bootstrap test are shown next to the branches. Only values higher than 50 are indicated. All positions containing gaps and missing data were eliminated from the dataset (Complete deletion option).
