Staphylococcus
Formerly Aurococcus.
Species in this genus
* Counted in the same healthy people as the species (whole-genome samples). All bars use the same 0–100% scale. A product with two Staphylococcus species counts once in the genus total.
Its species' DNA
Staphylococcus genomes run from 2.3M to 2.9M: small for gut microbes.
One reference genome per species; strains vary.
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 its species can do
A species counts when most of its strains can. Not measured in anyone's gut. 1 of its 27 species isn't in either source yet.

In healthy guts
Found in 3.1% of healthy people.
- largest Bacteroides 9.8%
- 2nd largest Phocaeicola 9.1%
- 3rd largest Segatella 6.4%
- 4th largest Bifidobacterium 6.2%
- 5th largest Faecalibacterium 5.4%
- 6th largest Alistipes 5.2%
- 7th largest Blautia 3.6%
- 8th largest Ruminococcus 3.0%
- top 20% Staphylococcus 0.03%
- 649 other microbes, each a sliver 32.3%
- 18.9%
On average, 0.03% of the microbes in a healthy gut: larger than 80% of genera’s 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 none 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.
