Vacuolating Toxin-Deficient H. Pylori and Related Methods

Summary

An isolated nucleic acid encoding the Helicobacter pylori vacuolating toxin, consisting of the nucleotides 101 through 3964 of the nucleotide sequence defined in the Sequence Listing as SEQ ID NO:1 is provided. An isolated nucleic acid from Helicobacter pylori comprising the nucleotide sequence defined in the Sequence Listing as SEQ ID NO:3 is provided. Isolated nucleic acids that selectively hybridize with the nucleic acids of the invention are provided. Also provided is a genetically altered mutant strain of H. pylori that does not express a functional vacuolating toxin. Purified proteins encoded by the nucleic acids of the invention are provided. A composition comprising an immunogenic amount of a protein or mutant strain of the invention in a pharmaceutically acceptable carrier is provided. A method of immunizing a subject against infection by H. pylori, comprising administering to the subject an immunogenic composition of the invention is provided.
