Hot off the press! Our latest paper led by @fernpizza.bsky.social, understanding how plasmids evolve inside cells. These small, self-replicating DNA circles live inside bacteria and carry antibiotic resistance genes, but also compete with one another to replicate. 1/

Here’s published version of our manuscript using GWAS to investigate tailocin sensitivity in Pseudomonas syringae. TL:DR pretty clear LPS is tailocin receptor but also that P.syringae often completely swaps out its entire O antigen biosynth pathway w/ recombination

It was great fun writing this review with @gemccallum.bsky.social , even if our conclusions are rather scary. Lots of important pathogen evolution must be occurring outside of the infection context...
Delighted to have this review out with @jpjhall.bsky.social!

We discuss the risk of transmission of antimicrobial resistance in the hospital sink drain microbiome, highlight studies providing evidence of transfer, and consider strategies to mitigate these risks 🪠🦠

Happy to finally have this out! It has been a fun side-project that we’ve been slowly working on for a while 🍜

I think it has turned out as a nice story, and demonstrates some important issues with historic taxonomic classifications in genome databases. All from investigating a contaminant! ⤵️
🚨 Very excited to finally say… 🚨

The story of Noodlococcus - the contaminant that started ContamClub - is available to read 📖🍜🦠

Do restriction-modification systems shape plasmid sequence composition? A group of plasmid-aficionados, led by Liam Shaw, started to explore this during the 2023 @embo.org Workshop on Plasmids in Trieste. Happy to have contributed to this work and be part of such a great team!
