Abstract excerpt

Helicobacter pylori seems universally distributed in all human populations, with high prevalence in the third world. Because H. pylori is an ancestral indigenous microbe of the human stomach, we hypothesized that its prevalence in isolated Amerindians would be high. A serologic study was performed on 19 Guahibo-Piaroa and 17 Warao in Venezuela, using H. pylori whole cell (WC) and CagA antigens from US strains....
