Helicobacter pylori is the most common cause of gastroduodenal diseases. The concept that
cagA-positive H. pylori is a risk factor for gastric cancer appears to be true only for H. pylori …

Background: Helicobacter pylori infection is closely associated with gastroduodenal
diseases. H. pylori infection with different vacA and cagA genotypes may result in divergent …

The frequency of Helicobacter pylori vacA alleles, cagA, and jhp0947 and their association
with types and advanced forms of gastritis in 143 first-degree relatives of gastric cancer (GC) …

AIM To evaluate effect of treatment failure on cagA and vacA genotypes in Helicobacter
pylori (H. pylori) isolates from Colombia. METHODS One hundred and seventy-six …

Helicobacter pylori (H. pylori) plays a crucial role in the pathogenesis of gastritis, peptic
ulcer, and gastric cancer. The presence of pathogenicity islands (PAI) genes contributes to …

Aim: To study the prevalence of cagA, vacA and babA2 genotypes in H. pylori strains
isolated from adults and children with gastroduodenal pathology. Material and Methods: 136 …

Background The vacuolating cytotoxin and the cytotoxinassociated protein, encoded by
vacA and cagA, respectively, are important virulence determinants of Helicobacter pylori …

AIMS: To determine the relation among the cytotoxin associated gene (cagA) and
vacuolating cytotoxin gene (vacA) status of Helicobacter pylori isolates, the associated …

BACKGROUND Helicobacter pylori infection is universally associated with gastritis, but only
sometimes with clinically significant disease. Candidate virulence markers seem to be useful …

Distinct virulence factors of Helicobacter pylori have been associated with clinical outcome
of the infection; however, considerable variations have been reported from different …
