Characterization of the Vacuolating Cytotoxin in Helicobacter pylori Strains Isolated from Iran
Objective: Helicobacter pylori (H.pylori) cytotoxin and its heterogeneity amongst strains hasbeen closely linked to the varying infection-associated clinical outcomes.In order to determinethe decisive role of the vacuolating cytotoxin (vacA) gene mosaicism in its corresponding geneexpression and phenotype, we aimed to characterize vacA alleles of d
