摘要

The present invention relates to recombinant polypeptides which constitute Helicobacter pylori surface-exposed antigens with an approximate molecular weight of 29 kDa. The invention furthermore provides nucleic acid molecules coding for the said polypeptides, as well as vectors and host cells comprising such nucleic acid molecules. The said recombinant polypeptides are useful for the diagnosis of H. pylori infections and for the manufacture of vaccine compositions which will elicit a protective immune response against such infections, said vaccine compositions being suitable for both therapeutic and prophylactic use.
