🔴 URGENTE: La Comunidad de Madrid suspende las ayudas predoctorales 2025

📌 Exigimos: convocatoria 2025 ya, mantener la inversión y una mesa de diálogo urgente.

🧵 Breve hilo detallando la situación en conjunto con las seis universidades públicas de la región.

Systematic profiling of growth interactions in human gut microbiome species Microbial interactions shape the composition and stability of the human gut microbiome. Yet, the molecular mechanisms underlying these relationships remain poorly understood. Here, we systematically p...

New preprint from the lab is out! 🥳

We systematically profiled all pairwise growth interactions between 36 representative human gut microbiome strains, and delved deeper into the molecular mechanisms behind specific growth interactions.

Really cool story from @lisamaierlab.bsky.social!
We are happy that @luuuprz.bsky.social (PhD student in our lab) contributed a small part.

New paper from the lab!
Led by Patrick Müller: we show that non-antibiotic compounds — but not macrolide antibiotics — can induce an efflux pump that protects Bacteroidaceae from macrolides.
A neat twist on drug–microbe interactions... www.tandfonline.com/doi/full/10....

Nutrient competition predicts gut microbiome restructuring under drug perturbations Systematic profiling of 707 drugs on their impact on stool-derived microbial communities shows that nutrient competition explains and predicts species shifts under drug treatment and that post-drug re...

How drugs reshape the gut microbiome? 💊🦠

Screening 707 drugs in gut microbial communities reveals nutrient competition as the key driver of compositional and metabolic shifts.

Systematic screen uncovers regulator contributions to chemical cues in Escherichia coli Transport machineries are crucial for antibiotic resistance, but their regulation by external cues is poorly understood. This study identifies environmental chemicals that regulate transporter transcr...

Finally out! A small screen helps understand a little more about how E. coli regulates major transporters, and reveals how caffeine induces phenotypical antibiotic resistance. Huge thanks to collab @andrenmateus.bsky.social (Umeå) and Christian L. Müller (Munich)!

What a fantastic week of science! And it couldn’t have finished in a better way, with Lucia winning one of the best poster awards! #EESMicrobiology

Couldn't be happier for receiving this prize from FEBS Letters after such a fantastic week at #EESMicrobiology! 🧫🔬🥰
