Helicobacter pylori cag pathogenicity island genotype diversity within the gastric niche of a single host.

Journal of medical microbiology - 1 May 2007

Abstract excerpt

cag pathogenicity island (PAI) integrity was investigated in isolates from multiple biopsies recovered from 40 patients in an attempt to determine the co-existence of a varying cagPAI-positive to cagPAI-negative ratio in a single host. Six biopsies were obtained from each patient during the same endoscopic session. cagPAI analysis included amplification of seven loci (cagA, cagE, cagG, cagM, cagT, HP0527 and...
