Helicobacter T pylon is a tale of a few individuals taking a stand against the medical wisdom …

Helicobacter pylori induces chronic inflammation of the gastric mucosa, but only a proportion
of infected individuals develop peptic ulcer disease or gastric carcinoma. Reasons …

Helicobacter pylori infects the stomachs of one in two humans and can cause sequelae that
include ulcers and cancer. Here we sequenced the genomes of 97 H. pylori isolates from 52 …

More and more convincing data link bacteria to the development of cancers. How bacteria
act as mutagens by altering host genomes, what are the different strategies they develop …

The ability of clinicians to wage an effective war against many bacterial infections is
increasingly being hampered by skyrocketing rates of antibiotic resistance. Indeed, antibiotic …

Helicobacter pylori is an important human pathogen that chronically colonizes the stomach
of half the world's population. Infection typically occurs in childhood and persists for …

Helicobacter pylori uses natural competence and homologous recombination to adapt to the
dynamic environment of the stomach mucosa and maintain chronic colonization. Although …

Extensive genetic variability resulting from a high mutation rate and frequent recombination
is a characteristic of Helicobacter pylori. Its average mutation rate is 1× 10− 6, similar to that …

Background: Helicobacter pylori gastritis increases gastric cancer risk. Microsatellite
instability‐type mutations are secondary to deficient DNA mismatch repair. H. pylori gastritis …

Background and aims Infection due to Helicobacter pylori causes many gastrointestinal
diseases including peptic ulcers and gastric carcinoma. Their treatment and prevention …
