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 🦠

Excited to share my latest review, now published in the Royal Society theme issue on ‘The ecology and evolution of bacterial immune systems' (available OA):

Defence systems encoded by core genomic islands of seventh pandemic Vibrio cholerae royalsocietypublishing.org/doi/10.1098/...
Defence systems encoded by core genomic islands of seventh pandemic Vibrio cholerae | Philosophical Transactions of the Royal Society B: Biological Sciences
Vibrio cholerae, the causative agent of cholera, has triggered seven pandemics, with the seventh pandemic emerging in 1961. The success of seventh pandemic El Tor (7PET) V. cholerae as a human pathogen is linked to its acquisition of mobile genetic ...

Oxygen levels can affect how resistance genes work, impacting antibiotic efficacy. This can be relevant for the most used ones: for example, resistance to fosfomycin varies with oxygen.

🚨🚨 New paper in @narjournal.bsky.social! 🍾

Excludons are pairs of overlapping genes that block each other’s expression (basically, reverse operons).

We built a tool to identify them in bacterial genomes using transcriptomic data, in an awesome collab led by Iñigo Lasa and Álvaro San Martín.

ExcludonFinder: mapping transcriptional overlaps between neighboring genes
Abstract. Bacteria regulate neighboring genes via overlapping transcription in untranslated regions (UTRs), forming excludons. This overlap leads to transc

Do plasmids evolve faster 🐇, slower 🐢, or just like chromosomes 🧬?

In our new paper, we tackled this question using theory, simulations, bioinformatics, and experiments!
