Abstract excerpt
OBJECTIVES: To determine whether the genotypes of virulent genes in Helicobacter pylori isolates and mucosal biopsy specimens differ in individuals, and to investigate whether different isolates from single hosts show strain differences. METHODS: Sixty-one Korean patients with H. pylori infection were enrolled. PCR and DNA sequencing for cagA, vacA, iceA, and oipA were performed using DNA extracted from H. pylori...
