Intestinal microbial dysbiosis is associated with Crohn’s disease (CD). However, the
mechanisms leading to the chronic mucosal inflammation that characterizes this disease remain …

Campylobacter jejuni is a prevalent gastrointestinal pathogen in humans and a common
commensal of poultry. When colonizing its hosts, C. jejuni comes into contact with intestinal …

The foodborne pathogen Campylobacter jejuni is the primary causative agent of gastroenteritis
in humans. In the present study a whole genome microarray of C. jejuni was constructed …

Inflammation alters host physiology to promote cancer, as seen in colitis-associated colorectal
cancer (CRC). Here, we identify the intestinal microbiota as a target of inflammation that …

The hypersensitive reaction to a pathogen is one of the most efficient defense mechanisms
in nature and leads to the induction of numerous plant genes encoding defense proteins. …

The role of pyoverdin, the main siderophore in iron-gathering capacity produced by Pseudomonas
aeruginosa, in bacterial growth in vivo is controversial, although iron is important for …

Iron affects the physiology of bacteria in two different ways: as a micronutrient for bacterial
growth and as a catalyst for the formation of hydroxyl radicals. In this study, we used DNA …

Eighty-eight Pseudomonas aeruginosa isolates, most of them from the Collection of Bacterial
Strains of the Institut Pasteur, Paris, were analysed for their pyoverdine-mediated iron …

A mechanism of ion transport across membranes is reported. Microbial transport of Fe 3+
generally delivers iron, a growth-limiting nutrient, to cells via highly specific siderophore-…

Cell density-dependent gene expression in Pseudomonas aeruginosa is controlled, in part,
by the quorum-sensing regulator LasR. lasR null mutants exhibited a reproducible 2-fold …
