Resumen CITTELLY P, Diana M et al. Los genotipos de Helicobacter pylori en gastritis no
atrófica difieren de los encontrados en úlcera péptica, lesiones premalignas y cáncer …

Several tests/methods for the infection, detection, and genotyping of Helicobacter pylori
have been developed in the past; all these differ in specificity and sensitivity and thereby …

Background Helicobacter pylori-associated gastroduodenal diseases depends on host
characteristics, environmental conditions and bacterial virulence factors, such as cagA, vacA …

The present report describes an analysis of two virulence genes of Helicobacter pylori. Parts
of the cagA gene, as well as parts from the signal (s) and middle (m) regions of the mosaic …

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 …

Helicobacter pylori infection is common in Alaska. The development of severe H. pylori
disease is partially determined by the virulence of the infecting strain. Here we present vacA …

Several reports have evidenced geographic differences in the prevalence of vacA
(vacuolating cytotoxin gene) alleles and cagA (cytotoxin-associated gene) status among …

Abstract e clinical outcome of Helicobacter pylori infection has been particularly associated
with virulence genotypes. ese genotypes are useful as molecular markers in the …

Background & Aims: Distinct allelic types of Helicobacter pylori vacA have been defined. The
geographic distribution of vacA alleles and cagA was assessed in this study. Methods: A …
