Youxingia wuxianensis
No reference ID-gene sequence in NCBI yet Data sources
Small for a gut microbe: longer than 35% of the 2,354 we have genomes for.
48% G+C, higher than 50% 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_014385085.1
What it can do
We don't have capability data for this microbe yet: it isn't in AGORA2's genome models, BacDive's lab tests or NJC19's published research. That's different from “not seen”: nobody has checked.
In healthy guts
Found in 12% 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%
- Youxingia wuxianensis 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 3 conditions 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.

“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.
