🔈Paper out! We turned the most fascinating phage host-switch mechanism, diversity-generating retroelements, into a programmable mutagenesis tool, DGRec. You can perform targeted hypermutation of any 50-200bp sequence directly in vivo in E. coli www.nature.com/articles/s41...

graphical abstract of the article the extended mobility of plasmids
Here's our new broad review on the extended mobility of plasmids, about all mechanisms driving and limiting their transfer. From conjugation to conduction, phage-plasmids to hitchers, molecular to evolutionary dynamics, ecology to biotech. The state of affairs. 1/9 academic.oup.com/nar/article/...
1/8 - New in @natcomms.nature.com !
☣️ Meet Yersinia enterocolitica (Ye) — a lesser-known but still dangerous cousin of Yersinia pestis.
We uncover how this invasive pathogen can survive and adapt for 14 years inside a human host under constant antibiotic pressure 👇

Hope it helps advance research and surveillance of this relevant bacterial pathogen. Thanks to @sylvainbrisse.bsky.social and BEBP and BIGSdb teams for making it possible!

Transformation, Recombination and horizontal transfer
The contribution of natural transformation for the acquisition of novel genes has been notoriously difficult to quantify because it relies on recombination (which is affected by other processes). Here's a first estimate : doi.org/10.1101/2025... (for the very busy: 1-6% of gene gains) #MicroSky

This preprint makes a point that is valid for a lot of machine learning approaches. Organisms or genes are linked by evolutionary history; they are not independent. This results in correlation between learning and test sets, and often in over-optimistic evaluations of the methods' outcome.

University websites are like distant stars, when you look at them you see the scientists as they used to be many years ago
First paper from my student Daria Frolova's PhD now on biorxiv:
www.biorxiv.org/content/10.1...
The key question: plasmids change structurally ~as fast as they mutate, so how can we decide whether 2 plasmids are "the same plasmid" for epi purposes?

New paper from the lab, the mysteries involving the genetic elements that move by being mobilized by other MGEs. Hitcher Genetic Elements are distinctive, ancient and diverse.

New job offer: we search a postdoc (bioinformatics) to work on mobile genetic elements and gene flow in bacteria, with a focus on antibiotic resistance within a consortium including bioinformatics, synthetic biology, epidemiology & biochemistry. See research.pasteur.fr/en/job/postd... #MicroSky
New preprint out now - stable bacterial strain nomenclature with Life Identification Numbers using a gene-by-gene approach. From our wonderful collaborators at the Institut Pasteur.

First step in a community project to provide a uniformly assembled, annotated and searchable set of bacterial genomes, our preprint on our initial release of 1.9 million genome assemblies+taxonomic estimates. (figure compares with previous 661k dataset)

I recently made a comic complaining that NASA refuses to listen to my good ideas for improving the Solar System (xkcd.com/2750).
To my delight, NASA’s Science Mission Directorate has sent me an actual expert panel evaluation of my “flatten the planets” proposal! Sadly, they decided not to fund it.
New from the lab. We were stuck studying plasmid mobility because we ignored most origins of transfer by conjugation. Using the occurrences of known oriT, we developed a method to find novel unrelated families. Works well. We now cover most conjugative plasmids of E coli, K pneumo & A baumannii.
