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_118554.1
Formerly Candidatus Clostridium anorexicus.
Mid-sized for a gut microbe: longer than 52% of the 2,354 we have genomes for.
60% G+C, higher than 74% of gut microbes.
To scale: if its ID gene were 1 cm long, its genome would stretch 21 meters. Yours would stretch 21 kilometers. One reference genome; strains vary. NCBI GCF_004154955.1
What it can do
- Can make butyrate A short-chain fatty acid that feeds the cells lining the colon.
Not seen in its genomes: make propionate, make lactic acid, ferment fiber, eat inulin, eat resistant starch, eat pectin, use lactose, feed on gut mucus, change bile acids, make B vitamins, make hydrogen sulfide, make methane.

In healthy guts
Found in 30% of healthy people.
- largest Segatella copri 6.2%
- 2nd largest Phocaeicola vulgatus 5.0%
- 3rd largest Faecalibacterium prausnitzii 4.7%
- 4th largest Bacteroides uniformis 3.2%
- 5th largest Agathobacter rectalis 2.5%
- 6th largest Alistipes putredinis 2.3%
- 7th largest Bifidobacterium longum 2.1%
- 8th largest Ruminococcus bromii 1.8%
- top 15% Intestinimonas butyriciproducens 0.02%
- 2,169 other microbes, each a sliver 56.6%
- 15.6%
On average, 0.02% of the microbes in a healthy gut: larger than 85% of species’ slices.
Every group, drawn the same way. Only some samples record age or sex, so each group says how many people it comes from. Tap one to see it above.
In conditions
Compared with healthy people in the same studies, it’s less common in 2 conditions and more common in 2 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.
