Our latest comment is now out! We discuss how the infection environment can shape #AntimicrobialResistance phenotypes, an important but often overlooked factor for predicting antimicrobial efficacy against bacterial pathogens 🦠🧫 #MicroSky @rug-lrs.bsky.social

How does treatment induced antibiotic resistance happen in real-world infections? We analysed 25k Pseudomonas isolates from 180 patients in a clinical trial to find out! TLDR: The ecological and evolutionary paths are surprisingly diverse & complex even in patients receiving identical treatment…

🧵 New preprint! Our 4-lab team evolved Streptococcus pneumoniae in antibiotic-treated mice of varying immune states and discovered something surprising: bacteria rarely evolved resistance. Instead, they found a different way to survive — by rewiring RNA turnover. 🔗 www.biorxiv.org/content/10.6...

New paper out in PNAS!!! 🎉 Do more plasmid copies mean faster evolution? 🧵 Dive into the story www.pnas.org/doi/10.1073/...

New preprint: www.biorxiv.org/content/10.6...

New preprint!👇 Pyruvate secreted by P. aeruginosa acts as a signaling molecule during infection, reducing oxidative stress, dampening immune activation and promoting persistence Bacterial metabolism isn’t just a background process but an active player in infection🦠🧫 www.biorxiv.org/content/10.6...

The @imili-micro.bsky.social project is such a beautiful and necessary initiative! I am really glad we could contribute. Special kudos to PhD student Lilibeth Torres who did the #Klebsiella drawing and wrote the text - @cbitoulouse.bsky.social

New preprint out! 📣🚨 We found that loss-of-function mutations in the carbapenem entry porin OprD of Pseudomonas aeruginosa do more than confer #AntibioticResistance: they reshape the bacterial membrane and interaction with the host, enhancing epithelial colonization capacity 🦠 #Microsky

We just opened the Bluesky account of the International Microbiology Literacy Initiative (IMiLI) headed by Ken Timmis. Follow us to know more about the initiative or even better become one of our volunteers to bring Microbiology to kids all ages around the world 🦠 🏫

Welcome to the social media account of the International Microbiology Literacy Initiative (IMiLI). Nearly 1,000 researchers freely contribute to the IMiLI project integrating microbiology into education providing downloadable resources for all. Explore at imili.org

This work is finally published! 🥳🧬 Plasmids are associated with very variable fitness costs in their different bacterial hosts. But, what is the contribution of each of the plasmid-genes in these host-specific effects? Study led by @jorgesastred.bsky.social, @sanmillan.bsky.social and myself! 1/14

New paper out! 🔈🔈📣📣 Plasmids promote antimicrobial resistance through Insertion Sequence-mediated gene inactivation. Combining experimental and computational approaches, we unveil how two of the most prevalent bacterial MGE accelerate the evolution of AMR. 🧵👇🏻 www.biorxiv.org/content/10.1...

Do plasmids evolve faster 🐇, slower 🐢, or just like chromosomes 🧬? In our new paper, we tackled this question using theory, simulations, bioinformatics, and experiments! 👇 Check out all the details in Paula’s thread! Hint: 🐇 (most of the time)

Our paper “Global dissemination of npmA mediated pan‑aminoglycoside resistance via a mobile element in Gram‑positive bacteria” is now in @natcomms.nature.com. Part of my freshly defended PhD, so doubly happy! 😄🎉 🧵 (1/14) www.doi.org/10.1038/s414...

Una nueva investigación identifica un mecanismo molecular que interviene en la pérdida de la resistencia bacteriana al antibiótico ciprofloxacino. 📰Lee aquí más información: bit.ly/4mMl2AN DOI: bit.ly/43uUtbT

Aquí os cuentan mis compañeras Susana de Lucas y Jennifer Palencia, de Comunicación y Cultura Científica del @cnb-csic.bsky.social, nuestro último trabajo. Describimos una estrategia de base evolutiva para eliminar la resistencia a ciprofloxacino en aislados clínicos de P. aeruginosa. Felices! 🤩

Check out this cool collaboration with @hernando-amado.bsky.social, just out in @natcomms.nature.com! We show that ciprofloxacin resistance rapidly declines in clinical P. aeruginosa strains under drug-free conditions, suggesting that ciprofloxacin restriction periods could help in clinics 🦠🧫

Ceftazidime-avibactam (a last resort drug) use selects multidrug-resistance and prevents designing collateral sensitivity based therapies against P. aeruginosa (no robust patterns emerge). Happy to see it published! 🥳 @cnb-csic.bsky.social @idisba.bsky.social www.nature.com/articles/s41...

Yesterday was a very special day where we celebrated the career and legacy of José Luis Martínez. We were able to learn some life lessons from him once again - he will be truly missed as an active researcher! It was a also pleasure to reconnect with so many friends at @cnb-csic.bsky.social 😁

The Pseudomonas Genome Database is now on Bluesky with the Pseudomonas.com web address! We encourage using the #pseudomonas hashtag to note interesting research #pseudomonas #bacteria #microsky #idsky #PsWatch

Just did my first Starter Pack, I think it can be useful. Let me know if you miss any journal and I will add it. Enjoy!! go.bsky.app/QPFZpj9

JL Martínez has been included on the @Clarivate Highly Cited Researcher list (Microbiology field) 2024. On November 28 we will pay homage to him for his great contributions to the Ecology and Evolution of Antibiotic Resistance field at @CNB_CSIC. clarivate.com/highly-cited...

Hello #MicroSky community, we would love to reconnect with you here. FOLLOW US for studies related with Microbiology and its applications 🧫 🦠

Jose Luis Martinez—not active in social media ☹️—a legend of Spanish Microbiology will retire soon. His friends & colleagues have organized this Nov 28 a warm homage in celebration of his lifelong dedication to Microbiology & his many contributions to Ecology and Evolution of antibiotic resistance 👏

Este premio PRAN a la mejor publicación científica es también de Pablo Laborda y JL Martínez. Gracias a la Agencia de Medicamentos y Productos Sanitarios, a la financiación y al director del CNB, Mario Mellado, por su apoyo a los jóvenes científicos que empezamos nuestra carrera independiente.

👋 Hi, #MicroSky community! I’m a postdoctoral researcher at the Technical University of Denmark, where we study the ecology and evolution of antibiotic resistance and the infection microbiology of Pseudomonas aeruginosa. Excited to join this space and share insights from my work!
