I also decided to give it a go to write this up in a way that's accessible without a strict scientific background: davvi36.wordpress.com/2026/02/20/p...

Plasmid Competition!

This blog post describes my recently published PLOS Biology paper – hopefully in an accessible format. It’s finally out and published in PLOS Biology: CRISPR-Cas is beneficial in plasmi…

Out now in @plosbiology.org : our big joint effort on the role of #CRISPR in plasmid competition. Read on for a really fun (I’m biased ok) analysis of how a defence system has new selective pressures when it’s mobile journals.plos.org/plosbiology/... 1/6

Two cartoon images of children with plasmids for faces about to fight. Commentators are saying "Plasmid-borne CRISPR-Cas systems provide significant defensive benefits" and "Yes, but toxin-antitoxin systems on competitor plasmids constrain the offensive CRISPR-Cas benefit"

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/ www.science.org/doi/10.1126/...

Intracellular competition shapes plasmid population dynamics

From populations of multicellular organisms to selfish genetic elements, conflicts between levels of biological organization are central to evolution. Plasmids are extrachromosomal, self-replicating g...

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 academic.oup.com/g3journal/ad...

Genomic correlates of tailocin sensitivity in Pseudomonas syringae

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 🪠🦠 doi.org/10.1038/s442...

🚨 Reminder! You have just over two weeks to submit an abstract, if you want to present at the @microbiologysociety.org meeting "Understanding and predicting microbial evolutionary dynamics" in Liverpool in November! #microsky 🦠🧫🔬

Jamie Hall@jpjhall.bsky.social · last yr.

‼️Update! Abstract submission is now open for the 2025 Liverpool UK @microbiologysociety.org meeting on "Understanding and predicting microbial evolutionary dynamics”! Deadline July 7th #microsky 🧪🧫🦠 microbiologysociety.org/event/societ...

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! ⤵️

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!
