Slackia faecicanis

Its ID gene (16S) · each bar is one letter A C G T NCBI 16S

What's this?

Zoomed in: letters 115–138

Its ID gene: the stretch scientists read to tell microbes apart. Each bar is one letter of its DNA. Every species has its own order of letters, so the pattern works like a fingerprint. Close relatives share most of it.

16S rRNA gene, V4 region: the 253 letters between the standard primers (515F/806R), which are the same in every species. One reference sequence; strains can differ by a letter or two. NCBI NR_042220.1

What’s typical · a description, not a comparison

In healthy guts

Not found in the healthy people we have. None of the healthy whole-genome samples carried it, so there is nothing typical to describe yet.

Compared within studies that had both

In conditions

Not yet compared in a study with healthy people. A condition shows up here once a study has people with it and healthy people of its own, 10 or more of each.

“Higher” is the study’s measure: on average, a bigger share of gut bacteria across everyone in the group, carriers or not. It isn’t how many people carry it. An association the authors report, measured once per person. It doesn’t mean a diet changes this microbe, or that the microbe affects health.
