A really great moment of scientific excitation with all the IP network all around the globe!


2018 International Pathogenic Neisseria Conference

Posted on Updated on

We will be present at the 2018 International Pathogenic Neisseria Conference

We will show our work on Monday and Thursday

Study of cell-shape diversity and evolution inside the Neisseriaceae family as a way to reveal new cellular functions.

Anti-Neisseria drugs screening start revealing the Achilles’ heel of N. meningitidis and N.

and I will moderate the Anti-Microbial Resistance and Therapies session the morning of Friday, Sept. 28.

New article: The mycobacterial cell envelope: a relict from the past or the result of a recent evolution?

Posted on Updated on


Our new article asking about the origins of the mycobacterial cell envelope just get accepted. You can find the article here

Do not hesitate to contact me if you want to debate about these hypotheses 😉

New article describing the only lytic phages known to infect the spirochete Leptospira

Posted on Updated on

With our colleagues of the Institut Pasteur Paris we sequenced and analysed the first genomes of the lytic phages LE3 and LE4 that can infect the saprophyte Leptospira biflexa using the lipopolysaccharide O-antigen as receptor. Bioinformatics analysis showed that the 48-kb LE3 and LE4 genomes are similar and contain 62% genes whose function cannot be predicted.

Félicitations à Antony pour ces deux bourses qui récompensent ton super travail!!!

Ces bourses vont permettent l’étude détaillée de l’évolution des Leptospires.

Bourse Postdoctorale:

Postdoctoral Fellowships (PDF) from NSERC and Postdoctoral research scholarship (B3X) from FRQNT

New talented Postdoc in the lab.

Posted on Updated on

From beginning of April the lab is lucky to host two talented posdocs:

Antony Vincent, who just received his Ph.D. from U. Laval (Steve Charettes) and has a enormous job to decipher the complex evolution of t he Leptospira genus in collaboration with the Réseau International des Institut Pasteur (RIIP) and specifically with the Mathieu Picardeau Lab in IP Paris.




Ahmed Khairalla a lecturer at the Department of Microbiology and Immunology, in the Faculty of Pharmacy, Beni-Suef University, Egypt, who received a fellowship from the Egyptian Ministry of Higher Education and Research. Ahmed will help the lab in the functional understanding of an enigmatic small protein from pathogenic Neisseria.
