Mucha suerte en la nueva etapa!!
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.

New paper out in PNAS!!! 🎉
Do more plasmid copies mean faster evolution?

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🦠🧫

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

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 🦠

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. 🧵👇🏻

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! 😄🎉
