Antigen of 49.6-kDa subunitpili protein of as a potential biomarker for early and rapid detection of the infection.

Background And Aim: infection has been identified as a major cause of peptic ulcer diseases, including gastric and duodenal ulcers, gastritis, chronic and gastric carcinoma, and even gastric lymphoma. studies using Western blotting analysis, hemagglutination test, adherence inhibition assays, and immunocytochemical staining revealed that the 49.6-kDa subunit pili protein of was considered an immunogenic protein.
