MethodsOne hundred H. pylori strains were isolated from patients with different gastrointestinal disease who admitted to Isfahan Al-zahra hospital. Vac A alleles were typed using PCR with specific primers. FindingsThere were four Vac A mosaicsms, including 28 for s1a/m1 (28%), 23 for s1b/m1 (23%), 26 for s1a/m2 (26%) and 23 for s1b/m2 (23%), s2 form was not found.
