Background Helicobacter pylori has diverged in parallel to its human host, leading to distinct phylogeographic populations. Recent evidence suggests that in the current human mixing in Latin America, European H. pylori (hpEurope) are increasingly dominant at the expense of Amerindian haplotypes (hspAmerind). This phenomenon might occur via DNA recombination, modulated by restriction-modification...
Helicobacter pylori infection is associated with gastric cancer (GC). The highest incidence rates have been described in Asia, but regional variations exist that do not match the distribution of infection prevalence rates. The aim of the study was to examine the possible contribution of H. pylori virulence factors to geographic differences in the incidence of GC across East and Southeast Asia. We...
