Noticeable relative abundance and variability of TM7, Synergistetes, and SR1 per body habitat. Representation of the relative abundances of the phyla TM7, Synergistetes (Synerg.), and SR1 among the subject population, expressed as percentage on a log scale (left). The high relative abundances of members of these phyla among the subjects, in particular for TM7, indicate a potential role in eubiosis. The body habitats and groups are labeled as in Figure 1.
