Jean-Christophe Marvaud is a lecturer in Microbiology at the Team Bactéries Pathogènes et Santé, Micalis Institut, Université Paris-Saclay. He obtained his Ph.D. degree in Microbiology at the Paris Sud University. His main research theme is the study of the host immune response to Clostridioides difficile infection. His skills include molecular biology (cloning, qRT-PCR, site-directed mutagenesis), bacteriology (experimentation in an anaerobic chamber), cell biology, and animal models (experimentation in conventional or axenic mice and hamsters).

Sylvie Bouttier is an associate professor in Microbiology and a member of the academic research team BaPS, Université Paris-Saclay, INRAE, AgroParisTech, the Micalis Institute, Orsay, France. She obtained her Ph.D. degree in Microbiology at the Faculty of Pharmacy, University of Paris-Sud. Her research interests and expertise include biofilms, antimicrobial activity, Clostridium difficile, adhesion and biofilms, and exopolymeric substances.

Johanna Saunier is a lecturer at the University of Paris-Saclay. She was awarded a doctorate in Materials Science and Engineering from INPG (1998–2001). In 2001–2003, she was temporary teaching and worked as a research attaché at the Evry Val d’Essonne University. Her research themes include polymeric materials intended for medical use: the effects of aging and sterilization on the surface segregation of low-molecular-weight compounds (blooming); the study of the polymorphism of additive-type migrants and implications for surface properties; the chemical and topological characterization of polymer surfaces (blooming, degradation, etc.): implications for surface properties and biocompatibility.

Imad Kansau is a professor at the University of Paris-Saclay (France). He is also an assistant practitioner at the Internal Medicine Service, Hôpital Antoine Béclère-Assistance Publique Hôpitaux de Paris (Clamart). He received his Ph.D. degree in Microbiology at the University of Paris VII in 1996. His research interests include infectious diseases, microbiology, the host response, Clostridioides difficile, inflammation cell signaling, flagella and other bacterial surface compounds, TLR signaling, and miRNA.
