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 252 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_113185.1
Mid-sized for a gut microbe: longer than 36% 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 18 meters. Yours would stretch 21 kilometers. One reference genome; strains vary. NCBI GCF_022846135.1
What it can do
- Can make propionate A short-chain fatty acid, mostly used by the liver.
- Mixed evidence Can make hydrogen sulfide A gas with the rotten-egg smell. Published research reports it; genome analysis didn't find it in its 1 genome.
Not seen in its genomes or lab tests: make butyrate, 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 methane.

In healthy guts
Found in 2.7% 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%
- Pyramidobacter piscolens under 0.01%
- 2,169 other microbes, each a sliver 56.7%
- 15.6%
On average, a sliver, under 0.01% of the microbes in a healthy gut.
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 none and more common in none. 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.
