Abstract: Certisafe is a novel Credential Authentication Process and System (CAPS), where a CertiSafe ID is generated once and only once the Issuer confirms the Authenticity of the Credential of a Candidate. This CertiSafe ID is a unique electronic ID, unique to the Candidate and also unique to the unique Credential, can be used repeatedly and endlessly in lieu of paper based copies that a Candidate usually submits to the Requestor through an application (physical I electronic). This method also purports to save precious paper and time for candidates each time they have to apply to an institution or an organization, by making redundant completely, the requirement of paper copies of the credentials and also their subsequent attestation. The verified credential, through CertiSafe ID, gives the Requesting organization the confidence of absorbing the right candidate and not a candidate with dubious credentials.

Abstract: A cagB gene of H. pylori is provided. This nucleic acid can be the nucleic acid consisting of nucleotides 193 through 1158 in the sequence set forth as SEQ ID NO:1, which is an example of a native coding sequence for CagB. This nucleic acid can also be in a vector suitable for expressing a polypeptide encoded by the nucleic acid. A cagC gene of H. pylori is provided. This nucleic acid can be the isolated nucleic acid consisting of nucleotides 1170 through 3830 in the sequence set forth as SEQ ID NO:3, which is an example of a native coding sequence for CagC. This nucleic acid can also be in a vector suitable for expressing a polypeptide encoded by the nucleic acid. Isolated nucleic acids that specifically hybridize with cagB and cagC are provided. CagB and CagC are associated with peptic ulceration and other clinical syndromes in humans infected with strains of H. pylori that express it.
