Blautia genomes run from 3.0M to 6.2M: large 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.

Compared within studies that had both
In conditions
Compared with healthy people in the same studies, it’s less common in 9 conditions and more common in 1 condition. 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.
