Helicobacter pylori (H. pylori) is a highly successful human pathogen that colonizes stomach
in around 50% of the global population. The colonization of bacterium induces an …

Helicobacter and Campylobacter species are Gram-negative microaerophilic host-
associated heterotrophic bacteria that invade the digestive tract of humans and animals …

Bacterial pathogens employ a general strategy to overcome host defenses by coordinating
the virulence gene expression using dedicated regulatory systems that could raise intricate …

In the nitrogen-fixing heterocyst-forming cyanobacterium Anabaena sp. PCC 7120, the ferric
uptake regulator FurA plays a global regulatory role. Failures to eliminate wild-type copies of …

Nickel homeostasis is important for pathogenic and ureolytic bacteria, which use this metal
ion as enzymatic cofactor. For example, in the human pathogen Helicobacter pylori an …

Significance: The successful adaptation of microorganisms to ever-changing environments
depends, to a great extent, on their ability to maintain redox homeostasis. To effectively …

Many bacterial regulatory genes appear to be dispensable, as they can be deleted from the
genome without loss of bacterial functionalities. In Helicobacter pylori, the hp1043 gene …

Helicobacter pylori is a gram-negative, microaerophilic, pathogenic bacterium and a
widespread colonizer of humans. H. pylori has developed mechanisms that enable it to …

Light modulates global features of the important human pathogen Acinetobacter baumannii
lifestyle including metabolism, tolerance to antibiotics and virulence, most of which depend …

The ferric uptake regulator (Fur) plays a major role in controlling the expression of iron
homeostasis genes in bacterial organisms. In this work, we fully characterized the capacity …
