Helicobacter pylori is the first formally recognized bacterial carcinogen and is one of the
most successful human pathogens, as over half of the world's population is colonized with …

In this review, we focus on a group of mobile genetic elements designated pathogenicity
islands (PAI). These elements play a pivotal role in the virulence of bacterial pathogens of …

Helicobacter pylori is one of the most successful human pathogens, which colonizes the
mucus layer of the gastric epithelium of more than 50% of the world's population. This …

Because previous studies have shown that a high molecular mass constituent of cranberry
juice inhibited adhesion of Escherichia coli to epithelial cells and coaggregation of oral …

Helicobacter pylori is a common component of the human stomach microbiota, possibly
dating back to the speciation of Homo sapiens. A history of pathogen evolution in allopatry …

Helicobacter pylori has a very plastic genome, reflecting its high rate of recombination and
point mutation. This plasticity promotes divergence of the population by the development of …

To look for evidence of intrafamilial infection, we isolated 107 Helicobacter pylori clones
from biopsied specimens taken from both parents and four children. We compared the …

In addition to their role in DNA repair, recombination events are associated with processes
aimed at providing the genetic variability needed for adaptation and evolution of a …

The availability of two complete Helicobacter pylori genome sequences and recent studies
of its population genetics have provided a detailed picture of genetic diversity in this …

Previous classification of Xanthomonas campestris has defined six pathovars (aberrans,
armoraciae, barbareae, campestris, incanae, and raphani) that cause diseases on …
