Abstract excerpt
BACKGROUND: Specific genotypes of several virulence factors of Helicobacter pylori (eg, cagA-positive, vacA s1, oipA "on" and babA-positive) have been reported to be predictors of severe clinical outcomes. Importantly, the presence of these genotypes correlates with each other. We hypothesized th...
