So excited to share our new preprint! 🎉🤩 Check it out to discover how we investigated the role and spatiotemporal dynamics of an essential Tad nanomachine during the lifecycle of our favorite bacterial predator, B.bacteriovorus 🦠 Many thanks to everyone who made this work possible!

New preprint! We show that the bacterial predator B. bacteriovorus deploys a unipolar Tad nanomachine for irreversible attachment to prey and invasion. @coralietesseur.bsky.social used CRISPRi+microfluidics to overcome barriers associated with essential systems in an obligate predatory lifestyle 🦠

I am delighted to share our latest preprint: doi.org/10.64898/202.... Fantastic work from my past and present lab members @flofournes.bsky.social, Sandra Martin and Nicolas Pellaton. Also many thanks to our precious collaborators @gruberlab.bsky.social and to @snsf.ch for funding this research.

Check out Snorre's latest preprint: www.biorxiv.org/content/10.6... I love this story: our 4-species synthetic bacterial community coexists across many simple environments and conditions. We show why (spoiler in the title)

Local peptidoglycan composition defines division site selection in Streptococcus pneumoniae

Nature Microbiology, Published online: 07 April 2026; doi:10.1038/s41564-026-02322-6Sequential peptidoglycan carboxylase activity of DacA and DacB generates a local peptidoglycan signature that recruits MapZ and establishes the division site at the Streptococcus pneumoniae cell equator.

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/...

Exclusion systems preserve host cell homeostasis and fitness, ensuring successful dissemination of conjugative plasmids and associated resistance genes

Abstract. Plasmid conjugation is a major driver of antibiotic resistance dissemination in bacteria. In addition to genes required for transfer and maintena

Check out the first preprint from our lab describing a direct molecular cross-talk between (p)ppGpp and c-di-GMP nucleotide messengers! Great work from first-author Corentin Jaboulay who was a postdoc in our lab, and great collaborations! @mmsb-lyon.bsky.social @cnrsbiologie.bsky.social
