Genome sizes · 4 Thomasclavelia species

Shortest we have Mycoplasmoides genitalium 0.6M

⋮ 687 shorter than any Thomasclavelia

Thomasclavelia spiroformis 2.5M

Thomasclavelia cocleata 3.0M

Thomasclavelia saccharogumia 3.1M

Thomasclavelia ramosa 3.5M

⋮ 939 longer than any Thomasclavelia

Longest we have Bradyrhizobium altum 9.8M

Thomasclavelia genomes run from 2.5M to 3.5M: mid-sized for gut microbes.

One reference genome per species; strains vary.

Their ID genes, lined up: shared stretches form solid stripes

16S gene, V4 region, from one reference sequence per species, aligned so the same positions line up. A blank is a gap: letters other species have and this one lacks. Switch to “Only where they differ” to fade the letters they share.

What’s typical · a description, not a comparison

In healthy guts

Not found in the healthy people we have. Our healthy numbers come from whole-genome samples, which name species. Thomasclavelia is only seen in 16S samples, which read genera differently, so it isn’t counted here.

Compared within studies that had both

In conditions

Compared with healthy people in the same studies, it’s less common in 2 conditions and more common in 10 conditions. Only studies that had both are counted.

A difference is an association: it doesn’t mean this microbe causes, prevents or treats any of these.
