The whole-cell-extract and the acid-extract preparations of Helicobacter pylori atrains isolated from peptic ulcer patients and the NCTC 11638 control strain were studied to compare their antigen profiles. Besides, the anti-H. pylori-antibody profile in serum from H. pylori-infected peptic ulcer patients were also studied to define the antigen stimulating apecific anti-H. pylori-antibody response in the infected patients. The whole-cell extract (WCE)and the acid-extract (AE) preparations showed a general antigenic homogeniety among the H.pylori strains isolated from the patients and the NCTC 11638 control strain. A humoral immune response against the infecting organism…
