🧬Phages in Toulouse — November 18–20, 2026! 🦠 We are delighted to announce the next edition of Phages.fr congress, Phages in Toulouse, bringing together the phage research community for 3 days of talks, presentations & scientific discussions! 📍 Toulouse, France 📅 Nov. 18–20
phages.fr
Réseau Bactériophage France
Bienvenue sur le site du réseau “Phages.fr” Le réseau “Phages.fr” regroupe des scientifiques qui travaillent sur les thématiques incluant les bactériophages dont l’étude des structures, interactions moléculaires & cellulaires, écologie & évolution, thérapie phagique et biocontrôle en santé humaine, végétale & animale et industrie ainsi que des Sciences humaines et sociales. Ces scientifiques appartiennent à différents instituts publics français de recherche tels que CNRS (principal financeur), INRAE, INSERM, ANSES, Institut Pasteur mais aussi de nombreuses universités (Bordeaux, Lyon, Marseille, Montpellier, Nancy, Paris, etc) et hôpitaux, avec aussi la participation de membres d’entreprises.

It's finally published! What a journey @brownlab.bsky.social and I have been on with this one (ask me about it over a pint 🍻). Super excited to be able to say that it's finally out in Trends (author gift link to follow)! 🦠🧫 #phagesky

If you have a Gmail account, you need to read this. Google's AI now scans your emails and attachments, bank statements, tax files, medical letters, all of it. It turned on by default, and there's a class-action lawsuit over how. Here are 5 moves to shut it off, the switch is hidden in two places:

When is an antiphage mechanism an evolved defence adaptation? This question has been on my mind for so long, because despite the field’s rapid progress there is currently no widely agreed framework in place to answer it. So @brownlab.bsky.social and I wrote this, and I'm happy to share the preprint!

Preprint alert📢! 
Ever wondered how much bacterial parasites influence evolutionary outcomes of their host? ➡️ We co-evolved two bacterial strains in conditions in which the costs and benefits of prophage carriage varied Here is what we found.

How do bacteria choose what type of defences to use against phages? We explored that question in the last paper I worked on as a postdoc at the Uni of Exeter @uniofexeteresi.bsky.social with Stineke van Houte, Stefano Pagliara and Edze Westra (not on Bluesky) doi.org/10.1098/rstb...

Great talk today @cbitoulouse.bsky.social from @annechevallereau.bsky.social- on the importance of surface receptors in phage adsorption and of intracellular phage defense mechanisms - and the relative importance of each of them in shaping phage host range &productive phage infection 🦠

Just out in The ISME Journal, a paper from my time in the Westra lab. We find that the extent of phage exposure shapes subsequent resistance dynamics over longer timescales (up to 30 days). And huge thanks to first authors @bridgetwatson.bsky.social and Loris for mammoth experiments!
