Abstract excerpt

Helicobacter pylori successfully colonizes the gastric niche. These bacteria produce a vacuolating cytotoxin known as VacA, which is codified by the vacA gene. This protein represents an important virulence factor. H. pylori strains have different vacA alleles, which show a variety of phenotypes that have been associated with gastrointestinal diseases. The aim of this study was to generate data about the...
