PLEASE SHARE. PhD Opportunity with me, Ben Raymond and Jan Engelstaedter and Andrew Letten at University of Queensland. Experimentally testing mechanisms of how temperature may change selection and spread of AMR in E. coli. Coupled with some advanced modelling and sequencing. 🧪🦠 #microsky

Our latest manuscript explores capsule exchangeability & phenotypic portability We didn’t directly address its role in #virulence ⏩️ that was already elegantly shown here—worth a look 👀👇🏻 doi.org/10.1371/jour... 🎯 Their results supports our plug-and-play model! Bonus: we kept 🐭 alive #microsky

How do multi-gene systems evolve across genetic backgrounds without disruptive epistasis? @julielebris.bsky.social @olayarendueles.bsky.social &co show the #Klebsiella capsule locus is a plug&play module that swaps with low fitness cost while preserving #virulence @plosbiology.org 🧪 plos.io/4s64Ko0

So happy to see this finally published in @plosbiology.org! This is the first chapter of @julielebris.bsky.social PhD thesis demonstrating how capsules are exchanged by plug-and-play dynamics w/ @epcrocha.bsky.social #microsky @klebclub.bsky.social Link below- Check out her 🧵 for more details!

Horizontal gene transfer is often depicted as a process distributing pre-existing functions to novel genetic backgrounds. Yet HGT can also increase the rate of functional innovation after transfer. Here's a brief review on the topic: ecoevorxiv.org/repository/v... #evosky #microsky

Pls re-post: My department @oxfordbiochemistry.bsky.social are recruiting for several new faculty positions (links below). Broad search in molecular biology/biochemistry, across prokaryotes and eukaryotes. Interested in understanding life at the molecular level, this job might be for you! 1/n

#OnThisDay in 1938, American evolutionary biologist Lynn Margulis was born. Margulis is most known for developing and popularising the endosymbiotic theory, which explains how eukaryotic cells evolved organelles from simpler prokaryotic organisms that resided within another and became incorporated.

New preprint out on bioRxiv! www.biorxiv.org/content/10.6... Can conjugative plasmids be used to control plasmid and pathogen spread? Follow me down the rabbit hole that led to this story 🧵

Alita Burmeister (@aburmeister.bsky.social) is looking to hire a postdoc (or potentially a PhD student) for projects on phage resistance and evolution. The position description is posted to the Eco-Evo Jobs wiki and also available on her lab's website (arburmeister.weebly.com).

Check out our latest preprint from @jnvmartinson.bsky.social and @leosong.bsky.social! 🌟🦠 We found that conjugative plasmids can actively eliminate recipient bacteria that resist plasmid acquisition. 🧵

Please check out our review on the impact of spatial structure in microbial ecosystems! In it, we discuss how spatial patterns impact microbial ecology and evolution, eventually impacting everything we see around us! See @marcelbaecker.bsky.social's amazing summary below :) 🦠 𝚂𝙿𝙰𝙲𝙴 𝙼𝙰𝚃𝚃𝙴𝚁𝚂 ! 🦠

✨If you have a story you would like to share with the community, please submit an abstract by Feb 16. ✨

Today we were thrilled to host @tatianadimitriu.bsky.social at @cbitoulouse.bsky.social @cnrsbiologie.bsky.social She discussed factors contributing to plasmid spread (defense systems, environmental factors…) - with @benoitjpons.bsky.social

Congrats to @carolinamicro.bsky.social for leading this study! We looked at genome rearrangements over short evolutionary timescales. Among other things, we found that genomes are highly syntenic within most species. However, several bacteria experienced sudden and massive genome rearrangements.

Bacteria chromosomes contain Genomic Islands that provide virulence, antibiotic resistance, MGE-defence,... They transfer between cells, but the mechanism of most remains elusive. Here we explore the conjugative capacity of these mysterious Genomic Islands. www.biorxiv.org/content/10.6...

#microsky #phagesky #phage At last! Great to see this one out: journals.plos.org/plospathogen... Here, we discovered a nested phage-bacteria network despite their high genetic and ecological diversity. Kudos to everyone involved, especially @chloe-feltin.bsky.social ! @phimresearch.bsky.social

1/n New paper alert! Bottlenecks are common in life cycles, but how do they shape the evolution of multiple cooperative traits at once? We tested this in M. xanthus under stringent vs relaxed bottlenecks.

Our first paper is out today in @natmicrobiol.nature.com! We introduce a prostate organoid model and show that UPEC invades prostate cells via FimH binding to the prostate-specific protein PAPP. A step toward targeted therapies against bacterial prostatitis. 🎉 #UTI #UPEC #Organoids #AMR
