(57) [Summary] [Problem] development of new diagnostic methods for H. pylori and H. pylori infection has a useful impact on vaccine design that can prevent and treat disease. py To provide purified proteins of lori cytotoxin and their genes, and their associated recombinants, such as vectors and host cells. A recombinant polypeptide comprising a contiguous sequence of at least 8 amino acids having the following properties: (1) The contiguous sequence of at least 8 amino acids includes at least one site, wherein the site is in a sequence consisting of the contiguous sequence of at least 8 amino acids or in the polypeptide, in a Helicobacter pyr. and (2) the contiguous sequence of at least 8 amino acids is derived from the disclosed amino acid sequence. |
