Colonisation density and topographic localisation of Helicobacter pylori do not depend on the cagA status

Abstract

Antibody titres do not correlate with H pylori density and there is no difference in density between cagA(+) and cagA(-)H pylori strains. In addition there is no difference in topographic localisation between cagA(+) and cagA(-) H pylori strains.
