Fantastic collaboration w/ @dbikard.bsky.social @audeber.bsky.social @rayanchikhi.bsky.social labs led by @jmouradesousa.bsky.social : We assessed the rates of variation of anti-phage systems in P4-like satellites and P2 helper phages. Quick conclusion: Huge variation! We focus on 4 key questions/5
Please RT:📢We are hiring a Post-Doc in Structural Biology to join our multidisciplinary team.
Project: study molecular mechanisms of horizontal gene transfer using cryo-EM and integrative structural biology.

Out today: We discovered new viral proteins that target immune signaling molecules, solely based on their AlphaFold-predicted shapes

Congrats Nitzan Tal and coauthors! Thank you Kranzusch lab for the fun collaboration!
Linking below previous thread on our findings
How does treatment induced antibiotic resistance happen in real-world infections? We analysed 25k Pseudomonas isolates from 180 patients in a clinical trial to find out! TLDR: The ecological and evolutionary paths are surprisingly diverse & complex even in patients receiving identical treatment…
We found a viral Trojan Horse: a virus can hide inside another virus.This one surprised us: deltaviruses don’t just borrow a helper virus. They can travel inside it.
A literal Trojan Horse “virus-in-a-virus” route into cells. 🤯 Kudos to 1st author @viroscope.bsky.social and co-authors !
New post-doctoral research position in my phage-host interactions (Phi) laboratory in @otagomicroimmuno.bsky.social at @universityofotago.bsky.social New Zealand. The project is focused on defences against jumbo phages. Please share and if interested apply using the link in the comments.
That being said, we do find that the strength of interactions that CAN be resolved over noise does decline for higher-order interactions. Above third order they cannot be reliably discriminated from empirical noise.
Even if higher-order interactions exist biologically and are strong, they will tend to contribute little to the total variance in small landscapes, simply because there are few of them.
Noise amplification and structural constraints severely limit our ability to detect them.
New preprint on the limits of detecting higher-order interactions in microbial communities.

We find that the dominance of additive and pairwise interactions on community function may not reflect biological simplicity, but fundamental limits of statistical detection.
Great work by Jamie Gorzynski and Josh-Harling-Lee from the group providing insights into the evolutionary origins of bacterial lineages. A collaboration with @jrpenades.bsky.social @wfigueroac3.bsky.social. #Staph Cell Reports www.cell.com/cell-reports...
Last year, we proposed a model of plasmid evolution via fusion and fragmentation (via mge mediated recombination) generating mosaics, by studying historical isolates. Excited to see a MASSIVE paper from @jrpenades.bsky.social , @epcrocha.bsky.social expanding on this

On this fabulous day celebrating André Citroën's birthday 🥖🚗, I’m happy to share my main paper from my postdoc in @jrpenades.bsky.social Lab.
If you want to hear about how plasmid evolution is driven by mobile genetic elements, please come and read this preprint!

1/ Antibiotic resistance causes ➕ than 1 M deaths each year and understanding why this happens is key to stopping it.
With #HealthResearch support, @sanmillan.bsky.social is investigating how different plasmids (DNA fragments) coexist in bacteria and confer resistance.

Anyone who’s tried deleting prophages in the lab by HR knows the difficulties of the task. Here we have an example of how HR-mediated natural transformation might hit the same hurdle in a more native context.

Klebs can evolve resistance to Colistin through mgrB mutation or by acquiring the mcr-1 gene. Both routes have similar fitness costs against a bacterial competitor, but mgrB mutations are associated with enhanced virulence.
