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 🦠

Carbapenem-resistance oprD mutations reshape Pseudomonas aeruginosa host-pathogen interactions during infection https://www.biorxiv.org/content/10.1101/2025.10.24.684370v1

New preprint!

Ever wondered why only a fraction of genomes encode CRISPR immunity? 🧬 🦠

Turns out CRISPR is rarely beneficial against virulent phages, being most beneficial against those for which resistance mutations are rare!

An epic effort by Rosanna Wright

Resistance mutation supply modulates the benefit of CRISPR immunity against virulent phages
Only a fraction of bacterial genomes encode CRISPR-Cas systems but the selective causes of this variation are unexplained. How naturally virulent bacteriophages (phages) select for CRISPR immunity has...

I'm not sure how relevant it is to be included within the top 2% of scientists worldwide by Stanford-Elsevier Ranking, but I've climbed from 1.5% to 1% in the last year (Microbiology and Evolutionary Biology fields) and I´m very happy!

New paper alert! 🚨

Plasmids promote bacterial evolution through a copy number-driven increase in mutation rate.

We combine theory, simulations, experimental evolution, and bioinformatics to demonstrate that mutation rates scale with plasmid copy number.

Let's dive in! 🧵👇
Plasmids promote bacterial evolution through a copy number-driven increase in mutation rate
Plasmids are autonomously replicating DNA molecules that stably coexist with chromosomes in bacterial cells. These genetic elements drive horizontal gene transfer and play a fundamental role in bacter...

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!
