Journal ArticleDOI
The potential probiotic Lactobacillus rhamnosus CNCM I-3690 strain protects the intestinal barrier by stimulating both mucus production and cytoprotective response
Rebeca Martín,Celia Chamignon,Nadia Mhedbi-Hajri,Florian Chain,Muriel Derrien,Unai Escribano-Vazquez,Peggy Garault,Aurélie Cotillard,Hang-Phuong Pham,Christian Chervaux,Luis G. Bermúdez-Humarán,Tamara Smokvina,Philippe Langella +12 more
TL;DR: The results show that CNCM I-3690 can physically maintain modulated goblet cells and the mucus layer and counteract changes in local and systemic lymphocytes and suggest that it restores impaired intestinal barrier functions via anti-inflammatory and cytoprotective responses.
Journal ArticleDOI

TL;DR: It is argued that the largest ecological entity within X. axonopodis is the pathovar, a first step of generalist diversification that spanned over the last 25 000 years and a second step of ecology-driven specialization occurred during the past two centuries.
Book ChapterDOI
Adhesion Mechanisms of Plant-Pathogenic Xanthomonadaceae
TL;DR: This chapter discusses recent findings on candidate adhesins of plant-pathogenic Xanthomonadaceae, including polysaccharidic and proteineous structures and their involvement in the formation of biofilms and their mode of regulation via quorum sensing.
Journal ArticleDOI
Sensing and adhesion are adaptive functions in the plant pathogenic xanthomonads
Nadia Mhedbi-Hajri,Armelle Darrasse,Sandrine Pigné,Karine Durand,Stéphanie Fouteau,Valérie Barbe,Charles Manceau,Christophe Lemaire,Marie-Agnès Jacques +8 more
TL;DR: The correspondence between repertoires of sensor and adhesin genes and pathovars and the rapid evolution of sensors andAdhesins shows that, for plant pathogenic xanthomonads, events leading to host specificity may occur as early as chemotactic attraction by host and adhesion to tissues.
Journal ArticleDOI
PecS is an important player in the regulatory network governing the coordinated expression of virulence genes during the interaction between Dickeya dadantii 3937 and plants
Nadia Mhedbi-Hajri,Nadia Mhedbi-Hajri,Pierrette Malfatti,Pierrette Malfatti,Jacques Pédron,Jacques Pédron,Stéphane Gaubert,Stéphane Gaubert,Sylvie Reverchon,Frédérique Van Gijsegem,Frédérique Van Gijsegem +10 more
TL;DR: It is shown that, contrary to Pectobacterium, the AHL-mediated ExpIR quorum-sensing system does not play a major role in the growth phase-dependent control of D. dadantii virulence genes.
