After 7 years, I’m saying goodbye to the lab that shaped a big part of my scientific journey. I earned here my PhD in Genomics & Bioinformatics, publishing research and building the lab’s bioinformatics pipelines from the ground up. A challenging and very rewarding experience.

After the great plasmids evolution session in the morning I followed up on the topic with my poster. Very nice discussions with colleagues that passed by to check it. Enjoyed it very much 🙏 #ESCMIDGlobal #genomics #bioinformatics #AMR #OneHealth

Diversification of bla OXA-48-harbouring plasmids among carbapenemase-producing Enterobacterales, 11 years after a large outbreak in a general hospital in the Netherlands
Introduction. Genes encoding OXA-48-like carbapenem-hydrolyzing enzymes are often located on plasmids and are abundant among carbapenemase-producing Enterobacterales (CPE) worldwide. After a large bla...

As we can expect PubMed dysfunction more and more or to be swamped with fake journals I suggest you get acquainted to this nice alternative: europepmc.org

Europe PMC is an archive of life sciences journal literature.

New pre-print!!! What types of genes end up on plasmids and why? The take home message of this paper is that beneficial genes move from plasmids to chromosome, causing the ecological value of plasmids to decay over time. www.biorxiv.org/content/10.1...

Chromosomal capture of beneficial genes drives plasmids towards ecological redundancy
Plasmids are a ubiquitous feature of bacterial genomes, but the evolutionary forces driving genes to become associated with plasmids are poorly understood. To address this problem, we compared the fit...

Graph Transformers (GTs) can handle long-range dependencies and resolve information bottlenecks, but they’re computationally expensive. Our new model, Spexphormer, helps scale them to much larger graphs – check it out at NeurIPS next week, or the preview here! [1/13] #NeurIPS2024
