📣 preprint alert! We sampled #klebsiella isolates from💩 patients when they entered the hospital & 🩸 after development of infection. 🎯 We tracked phenotypic changes & correlate them w genotypic changes. @klebclub.bsky.social -in collab with Clermont-Ferrand lab #microsky 🧵 doi.org/10.64898/202...

The distinction between virulent & temperate phages gets fuzzier if one can find so many virulent phages in the sequences of bacterial genomes coming from standard lab "pure" cultures. Check Peter's thread on our work and the N&V by Carson & Hynes: doi.org/10.1038/s415... #phagesky #microsky

🎉 New year, NEW PREPRINT! Bacteria exhibit astonishing genetic diversity, but where do new genes come from? My best friend Arya Kaul (/labmate in the @baym lab) investigates how advantageous deletions can spawn new genes - "deletion-born fusions." 🧵:

Booking trains, and once again my eurostar tickets will be twice as cheap as the UK part of my journey (Scotland-London, similar from Cornwall). It's not like the Eurostar has to go through a tunnel digged within a Cretaceous layer under the sea or anything.

Beautiful work from Jay Winans in the Nadell Lab @dartmouthartsci.bsky.social showing IncF plasmid pED208 spreading like wildfire through E. coli biofilms www.cell.com/current-biol...

Bacterial genomes encode a rich repertoire of antiphage systems, but we still know surprisingly little about when these systems are actually expressed. In this preprint, Lucas Paoli et al, ask what shapes antiphage systems expression in native contexts. www.biorxiv.org/content/10.6...

Our story on plasmid streamlining is now published in PLoS Biology! With @andrewmatthews.bsky.social and @sonjalehtinen.bsky.social #MicroSky #Mevosky journals.plos.org/plosbiology/...

Conjugative plasmids help spread AMR genes. @andrewmatthews.bsky.social @sonjalehtinen.bsky.social & @tatianadimitriu.bsky.social show that #AMR loss in evolving populations involves streamlined #plasmids that gain a transmission advantage by deleting AMR genes @plosbiology.org 🧪 plos.io/48NM0BL

What is the best strategy to win any contest? Eliminate your opponents of course. Recently, my friend @fernpizza.bsky.social showed how plasmids compete intracellularly (check out his paper published in Science today!). With @baym.lol, we now know they can fight. www.biorxiv.org/content/10.1...

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/...

Published in Current Biology! P. aeruginosa can use its filamentous phage to inhibit competitors but high phage production is susceptible to cheater miniphage invasion. Subsequent phage tragedy of the commons can lower bacteria and phage fitness. Link: authors.elsevier.com/c/1lt5I3QW8S...

Exclusion systems, far from slowing down plasmid spread, are in fact essential to preserve host cell viability and thereby ensure the successful dissemination of conjugative plasmids and antibiotic resistance genes. @nfrk92.bsky.social @narjournal.bsky.social academic.oup.com/nar/article/...

Super paper from the mighty Mia Winkler, @genomarit.bsky.social and Iren Lohr. "We have previously shown that there were relatively few strain-sharing events across ecological niches...plasmid-sharing is considerably more common across niches than strain-sharing. " www.biorxiv.org/content/10.1...

Does your lab perform killing assays? TL;DR: we’ve identified a problem that can bias the outcome of killing assays, making antagonism look stronger than it really is. Adding a simple extra step can mitigate this bias!  Out now at #MicrobioJ www.microbiologyresearch.org/content/jour... 1/n

It is funny reading papers from labs with different interests and approaches, which consider variation in conjugation rates in opposite ways: on one side (more molecular genetics), dismissing anything less than 10-fold or 100-fold as ‘not really involved in transfer’

New pre-print from my lab! Plasmids link antibiotic resistance and phage defense. E.coli plasmids are hotspots for both antibiotic resistance and phage defense. Phage therapy has the potential to accidentally select for antibiotic resistance!!! #microsky#AMR#phage www.biorxiv.org/content/10.1....
