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 …

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 …

Rearrangement of genomic DNA via homologous recombination provides an alternative
mechanism of gene regulation that is essential for successful colonization of the gastric …

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

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 infects the stomach of about half of the world's human population,
frequently causing chronic inflammation at the origin of several gastric pathologies. One of …

The pathogenic bacterium Helicobacter pylori infects half of the human population and it is
one of the most genetically diverse bacterial species known. The unusual combination of …

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 …

Genetic recombination can be important evolutionarily in speeding the adaptation of
organisms to new environments and in purging deleterious mutations. Here, we describe …

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 …
