I am excited to share our preprint! we use synthetic human gut communities to reveal crucial ecosystem-level dynamics that drive major gut microbiota signatures. Thanks to the support of @MoualiYoussef and Strowig lab biorxiv.org/content/10.1101/…

S. copri keeps pace with modern lifestyles
Subset of Segatella copri strains have acquired an additional oxygen regulator via horizontal gene transfer, which confers increased oxygen tolerance. These strains are more prevalent in industrialized countries

I'm thrilled to share our latest manuscript, published in @Nature!!
➡️ doi.org/10.1038/s415...
We analyzed data from over 34,000 participants from UK and US, revealing strong associations between specific gut bacteria and markers of cardiometabolic health and dietary habits.

Exciting new #GutMicrobiome study with over 30,000 participants! @fasnicar & team link microbes to metabolic health markers & alter their abundance with diet interventions, teaming up with @timspector's ZOE app microbiome testing.
These big datasets are what we need!

The unfolding drama between neighboring bacteria:
@Goodman_lab ID mechanism used by human gut commensals to antagonize related bacteria. Secreted effector Bte1 alters the protein-folding machinery of targeted cells, causing substrate aggregation & toxicity

Bacterial small RNA makes a big impact for gut colonization
Monzel & Desai @LIH_Luxembourg highlight work of @MoualiYoussef @StrowigLab IDing SrcF, sRNA from S. copri that promotes colonization by regulating bacterial degradation of dietary carbohydrates

Segatella copri ist ein weitverbreitetes #Darmbakterium, aber noch relativ wenig erforscht. Eine Studie von @StrowigLab, @MoualiYoussef in Kooperation mit @JoergLab identifiziert jetzt eine small #RNA, die eine Schlüsselrolle bei der Besiedelung spielt.

Just like a musician needs the right sheet music to play beautifully, a gut bacterium needs a specific signal to flourish.

RNA world of Prevotella, now Segatella, gut bacteria unfolding! Includes an sRNA essential for colonization.
Great work from the @StrowigLab. I am proud to say that three of my former students and postdocs (El Mouali, Tawk, Ponath) contributed to it.
