In total, 567 (81.23%) patients with H. pylori infection were positive for the cagA gene, 443 (63.46%) were positive for the vacA gene, and 370 (53.0%) were positive for both. The cagA genotype was significantly more common in patients with chronic gastritis and peptic ulcers (78.99% and 79.41%, respectively) than the vacA gene (51.48% and 55.88%, respectively) and combined genotypes (32.34% and 47.05%, respectively). Moreover, the cagA genotype was significantly more common in patients with type 4 or 5 gastric mucosa patterns (69.49% and 76.31%, respectively).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The cagA genotype is the main cause of serious inflammation of the gastric mucosa.
