  • Patent number: 9173932
    Abstract: The disclosure pertains to conjugates of the capsular polysaccharide of Vibrio cholerae O139, or a structurally and/or immunologically related oligo- or poly-saccharide, and a carrier. These conjugates are useful as pharmaceutical compositions and/or vaccines to induce serum antibodies which have bactericidal (vibriocidal) activity against V. cholerae, in particular V. cholerae O139, and are useful to prevent, treat and/or reduce the severity of disease caused by V. cholerae infection, such as cholera. The present disclosure also relates to diagnostic tests for V. cholerae infection, and/or cholera caused by V. cholerae infection, using one or more of the oligo- or poly-saccharide-carrier conjugates or antibodies described above.

  • Patent number: 5738855
    Abstract: The present invention is a modified plant, fruit or synthetic oligo- or polysaccharide which has been structurally altered so as to render the modified saccharide antigenically similar to the Vi of Salmonella typhi. The modified saccharide may be conjugated to a carrier to form a conjugate that is immunogenic against S. typhi. Antibodies produced in response to the immunogenic conjugate are protective against typhoid fever. Methods are provided for making the modified saccharide and the immunogenic conjugate.
