Helicobacter pylori is a gram-negative, slow-growing, microaerophilic, spiral bacterium. It is
one of the most common human gastrointestinal pathogens, infecting almost 50% of the …

All organisms have pathways that repair the genome, ensuring their survival and that of their
progeny. But these pathways also serve to diversify the genome, causing changes at the …

Helicobacter pylori is a gram-negative pathogenic bacterium that colonises the human
stomach. The chronic infection it causes results in peptic ulcers and gastric cancers. H. pylori …

The Helicobacter pylori genome is more thoroughly mixed by homologous recombination
than by any other organism that has been investigated, leading to apparent “free …

Helicobacter pylori, a Gram-negative pathogen associated with ulcers, chronic gastritis, and
gastric cancers, has been a resident of the human stomach since early human history [1] …

Helicobacter pylori is one of the most common pathogenic bacteria infecting humans. It is
estimated that more than half of the human population is chronically colonized with this …

Many organisms respond to DNA damage by inducing expression of DNA repair genes. We
find that the human stomach pathogen Helicobacter pylori instead induces transcription and …

Helicobacter pylori, a pathogenic bacterium that colonizes in the human stomach, harbors
DNA repair genes to counter the gastric environment during chronic infection. In addition, H …

Helicobacter pylori is a genetically diverse bacterial species, owing in part to its natural
competence for DNA uptake that facilitates recombination between strains. Inter‐strain DNA …

Background Extensive genetic diversity and rapid allelic diversification are characteristics of
the human gastric pathogen Helicobacter pylori, and are believed to contribute to its ability …
