  • Patent number: 11998608
    Abstract: There is provided a molecule comprising a chain of seven or more contiguous units of 4,6-dideoxy-4-acylamido-?-pyranose each pair of units joined by a C1-C2 or a C1-C3 link, the chain having a terminal end and a reducing end, wherein the pyranose ring in the unit of the chain most distal from the reducing end is linked to a cap structure. The cap structure is not a 4,6-dideoxy-4-acylamido-?-pyranose. There are also provided vaccine compositions comprising the molecule and methods of vaccinating an animal against infection by a Brucella organism, including methods of distinguishing between a vaccinated and an infected animal. There are further provided novel methods of detecting the presence in a sample of an anti-Brucella antibody.

  • Patent number: 10207006
    Abstract: There is provided a method of detecting in a sample the presence of an anti-M and/or anti-A and/or anti-C/Y antibody, the method comprising contacting the sample with a diagnostic conjugate provided according to the invention, comprising an oligosaccharide which comprises at least two units of 4,6-dideoxy-4-acylamido-?-pyranose and comprising at least one -(1-3)- link between adjacent 4,6-dideoxy-4-acylamido-?-pyranose units, in which the carbon at position 5 in the pyranose is linked to an R group, where R is independently selected from —CH2OH, —H or an alkyl group having at least one C atom, the oligosaccharide being covalently linked to a non-saccharide molecule or to a surface.
