How do you react when your favorite microbe is renamed by taxonomists who are completely outside your field—and who ignore the community that actually works with it? Here is our clear answer re the case of Pseudomonas putida KT2440 👉🏻 journals.asm.org/doi/10.1128/...
Closing out my year with a journal editor shocker 🧵
Checking new manuscripts today I reviewed a paper attributing 2 papers to me I did not write. A daft thing for an author to do of course. But intrigued I web searched up one of the titles and that's when it got real weird...
New in JB: Trottier, Déziel et al. show that despite the conservation of the PqsE sequence of P. aeruginosa and some key conserved functions, including and essential role for HAQ biosynthesis, this protein has different impacts across strains of Pa.

New lab paper!
Andrew Frando describes how MexT alters the quorum sensing cascade in P. aeruginosa. /1
With Nicole Smalley; two undergraduates, Jamal Omar and Bobby Parsek; and @dezieleric.bsky.social, @mariecg.bsky.social, and Mylène Trottier at INRS in Montreal

Plus que 10 jours avant la fin des soumissions des résumés pour le BiSP qui aura lieu le 5-6 novembre 2025 à l'Université de Sherbrooke. Nous aurons aussi la chance de recevoir @lalouxlab.bsky.social et @bjesseshapiro.bsky.social
Partagez! @micrhub.bsky.social

What to know more about #biosurfactants but do not know where to start? We are publishing a «Primer» on the topic! Great contribution from PhD student Maude Dagenais Roy www.microbiologyresearch.org/content/jour... Thanks to @microbiologysociety.org
The 3rd International #Biosurfactants Conference will take place in Aachen, Germany September 8 -10 2025. Academia and industry will discuss the latest developments, and share cutting-edge insight in this exciting field of microbial #biotechnology #microsky biosurfactants.uni-hohenheim.de/en
🌿Un projet scientifique innovant au Carré Laval

Our new big review on Pseudomonas aeruginosa. Hope you enjoy reading it. www.nature.com/articles/s41...
Great new resource for Quorum sensing enthusiasts: a database linking LuxI-type synthases to their AHLs journals.asm.org/doi/full/10....
🤦🏻♀️
New work from the lab! Sometimes going beyond prototypical strains such as PAO1 or PA14 tells a more complex and nuanced story.
PqsE is conserved and functionally relevant in Pseudomonas aeruginosa https://www.biorxiv.org/content/10.1101/2025.05.16.654539v1
Yeahhh ! 🎉
I got hit by some rather sudden and extreme financial hardship so if anyone is in need of remote wetlab contract research, strictly BSL1, do let me know. Currently scrambling for gigs.

Good job @pmlcoulon.bsky.social !
Colony morphotype variation in Burkholderia: implications for success of applications and therapeutics
#JBacteriol by @pmlcoulon.bsky.social et al
journals.asm.org/doi/10.1128/...
Réservez les dates! Le BiSP (bactériologie intégrative, symbiose et pathogénèse) aura lieu le 5 et 6 novembre à l'Université de Sherbrooke - un événement qui sera en "symbiose" avec le MicrHub, rencontre annuelle de tous les microbiologistes de Sherbrooke. À ne pas manquer!
New in JB: Coulon, Deziel, et al. explore quorum sensing and DNA methylation in phase variation in Burkholderia clinical isolates.

@asm.org #JBacteriology
Le professeur Éric Déziel fait figure de pionnier dans l’étude des #biosurfactants. Avec son équipe, il a mis au point une méthode innovante d'évolution dirigée, inspirée de la sélection naturelle, pour améliorer leur production et rendre leur utilisation plus accessible.

The International Workshop on ‘Cell-cell communication in bacteria’ (CCCB25) to be held in Trieste, Italy, October 28-30 2025 is now open for abstract submission and registration www.icgeb.org/cell-cell-co...
Some abstracts will be selected for oral presentations. #quorum-sensing
A new line of research in the lab over recent years! We start with a review article, by postdoc Nasim Sedighian as lead author - Ecofriendly Control Strategies Against Clavibacter michiganensis, the Causal Agent of Bacterial Canker of Tomato | Plant Disease apsjournals.apsnet.org/doi/10.1094/...
New paper out! Phenotypic variation is a feature of several Burkholderia species. We found that quorum sensing and adenosine DNA methylation are two antagonistic systems independently controlling phase variation in B. ambifaria. Great work by @pmlcoulon.bsky.social journals.asm.org/doi/10.1128/...
Excited to share this article with the community! Many thanks to @dezieleric.bsky.social for allowing me to start this work during my PhD and for his continued support. I also appreciate @mariecg.bsky.social for her amazing contribution and constant support!
