Welcome ANIS AIT ALI YAHIA from Algeria, University of sciences and technology Houari-boumediene (USTHB), that will work on cell shape evolution in the Neisseriaceae family.


Influence of LPS modifications on OMVs production

Posted on Updated on

Our paper in j. Bact is online (not proof edited):

PmrC/EptA and CptA negatively affect outer membrane vesicle production in Citrobacter rodentium.

I am thankful for this nice last collaboration with a talented researcher Hervé le Moual, and congratulation to the amazing student Anshul Sinha (and Sammy Nyongesa)!!!!

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.
