[Genotyping of Helicobacter pylori virulence factors vacA and cagA in individuals from two regions in Colombia with opposing risk for gastric cancer].

Biomedica : revista del Instituto Nacional de Salud - 1 Jan 2000

Trujillo Esperanza, Martínez Teresa, Bravo María Mercedes

Abstract excerpt

INTRODUCTION: The overall prevalence of Helicobacter pylori infection is high in Colombia; however, in the country´s Andean region, gastric cancer rates far surpass those in coastal areas. Helicobacter pylori genotypes cagA positive and vacA s1 and m1 are associated with an increased risk of gastric cancer. OBJECTIVE: To compare the distribution of H. pylori genotypes associated with virulence in two regions in...
