CagA and vacA allelic combination of Helicobacter pylori in gastroduodenal disorders

ConclusionIn this work, Western type (EPIYA-ABC and ABCC motifs) cagA, vacA s1m1 combinations have been demonstrated as the dominant genotype in the tested Ahvazian H. Pylori strains. Also the participation of cagA gene and vacA s1m1 genotype in development and severity of gastric disorder was well evident. Therefore, infection with H. pylori strain containing the cagA gene or the vacA s1m1 genotypes could be associated with increased risk of GC. This is the first study in our area that reports the high incidence and diversity of allelic combination of cagA and vacA genes in gastroduodenitis patients.
