The bacterial pathogen Helicobacter pylori has co-evolved with humans and colonizes
approximately 50% of the human population, but only causes overt gastric disease in a …

Chemotaxis enables microorganisms to move according to chemical gradients. Although
this process requires substantial cellular energy, it also affords key physiological benefits …

Chemoreceptors in bacteria detect a variety of signals and feed this information into
chemosensory pathways that represent a major mode of signal transduction. The five …

This review aimed to investigate the role of Helicobacter pylori flagella on the pathogenicity
of this bacterium in humans. Helicobacter pylori is a flagellated pathogen that colonizes the …

Background Helicobacter pylori is well adapted to colonize the epithelial surface of the
human gastric mucosa and can cause persistent infections. In order to infect the gastric …

Bacterial chemotaxis is a biased movement of bacteria toward the beneficial chemical
gradient or away from a toxic chemical gradient. This movement is achieved by sensing a …

The gastric pathogen Helicobacter pylori interacts intimately with the gastric mucosa to avoid
the microbicidal acid in the stomach lumen. The cues H. pylori senses to locate and colonize …

Helicobacter pylori is the main pathogenic bacterium involved in chronic gastritis and peptic
ulcer and a class 1 carcinogen in gastric cancer. Current research focuses on the …

The human stomach is a formidable barrier to orally ingested microorganisms and was long
thought to be sterile. The discovery of Helicobacter pylori, a carcinogenic bacterial pathogen …

Highlights•The Helicobacter pylori chemotaxis system includes classical and auxiliary
chemotaxis proteins.•H. pylori senses several host and bacterial ligands through four …
