First preprint of the Grognot Lab 🎉 in collab. with the amazing Gitai and Wingreen labs (Princeton U.)
🔬👨‍💻We used single-cell 3D tracking of V. cholerae, complemented by MD simulations, to better understand how being curved helps the pathogen navigate mucus-mimicking media.🦠

Cell-body curvature modulates stall frequency to enhance Vibrio cholerae swimming and chemotaxis through hydrogels
The swimming motility of bacterial pathogen Vibrio cholerae is a virulence factor that aids in breaching the mucus layer of the small intestine. V. cholerae cells have a curved cell shape and previous...

JB Editor's Choice: Waller, Ribardo & Hendrixson show that flagellar length impacts function, with short flagella slowing swimming and reducing host colonization, indicating the important of regulating the lenght of the filament.

Finally online!
Our latest research is out @nature.com: We show that non-antibiotic drugs can disrupt colonization resistance, raising the risk of enteric infections.

Non-antibiotics disrupt colonization resistance against enteropathogens
Nature - Non-antibiotic drugs from a wide range of therapeutic classes can alter the ability of gut commensals to resist invasion by enteropathogens, a previously underappreciated side effect of...

Finally out! A small screen helps understand a little more about how E. coli regulates major transporters, and reveals how caffeine induces phenotypical antibiotic resistance. Huge thanks to collab @andrenmateus.bsky.social (Umeå) and Christian L. Müller (Munich)!

Systematic screen uncovers regulator contributions to chemical cues in Escherichia coli
Transport machineries are crucial for antibiotic resistance, but their regulation by external cues is poorly understood. This study identifies environmental chemicals that regulate transporter transcr...

Are you a recent PhD (or soon to be PhD) from outside Canada looking to do a postdoc in Quebec?

Get in touch if you are excited about microbes, evolution, ecology, genomics (or all of the above!) and I'd be happy to help develop a project together!
