prevalence of helicobacter pylori vaca, caga and icea genotypes in south african patients with upper gastrointestinal diseases.clinical response to helicobacter pylori infection may be determined by specific virulence-associated genotypes which varies geographically. the aim of this study was to investigate the diversity of putative virulence markers of h. pylori; caga, vaca and icea in the eastern cape province of south africa. one hundred h. pylori strains obtained from dyspeptic patients were used. gastric biopsies were obtained from 254 dyspeptic patients. h. pylori was cultured and strains were studied. bacterial g ...201020529658
