Horizontal gene transfer (HGT) is arguably the most conspicuous feature of bacterial
evolution. Evidence for HGT is found in most bacterial genomes. Although HGT can …

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 …

Accurate strain identification is essential for anyone working with bacteria. For many
species, multilocus sequence typing (MLST) is considered the “gold standard” of typing, but …

Gut microbiota are shaped by a combination of ecological and evolutionary forces. While the
ecological dynamics have been extensively studied, much less is known about how species …

H. pylori is one of the most common bacterial infections in human beings, and its discovery
20 years ago altered the diagnosis and treatment of gastroduodenal disease. This review …

Pathogenic Escherichia coli cause over 160 million cases of dysentery and one million
deaths per year, whereas non‐pathogenic E. coli constitute part of the normal intestinal flora …

Recombination is a powerful evolutionary force that merges historically distinct genotypes.
But the extent of recombination within many organisms is unknown, and even determining …

Neisseria meningitidis is a major cause of bacterial septicemia and meningitis. Sequence
variation of surface-exposed proteins and cross-reactivity of the serogroup B capsular …

Helicobacter pylori is highly adapted for colonization of the human stomach and is present in
about half of the human population. When present, H pylori is usually the numerically …

Helicobacter pylori are bacteria that have coevolved with humans to be transmitted from
person to person and to persistently colonize the stomach. Their population structure is a …
