Coupling DNA processing to early gene expression drives antibiotic resistance plasmid dissemination
The rapid global spread of antibiotic resistance is mediated by conjugative plasmids, yet how these elements establish immediately after entering new bacterial hosts remains poorly understood. Here we...

Our preprint is now published in PNAS! This came together thanks to a great collaboration with Antoine Hocher and a strong team effort from the Le Lab. Thank you to the reviewers and to everyone who helped improve it. I hope ParB aficionados will enjoy it. www.pnas.org/doi/10.1073/...

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/...

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

#MicroSky Summer read! Predatory bacteria kill and eat other bacteria. Their deadly actions come in many flavors, often via direct physical contact between predator & prey 🧛 How do they do it? Our review 📖 @coralietesseur.bsky.social @ysantin.bsky.social www.sciencedirect.com/science/arti...

Strategies and mechanisms of contact-dependent predation in bacteria
Predatory bacteria kill other bacteria to acquire nutrients. Among diverse strategies to kill and feed on prey, contact-dependent predation stands out…
