Patent number: 11998608Abstract: 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.Type: GrantFiled: May 11, 2021Date of Patent: June 4, 2024Assignees: THE SECRETARY OF STATE FOR ENVIRONMENT, FOOD AND RURAL AFFAIRS, THE GOVERNORS OF THE UNIVERSITY OF ALBERTAInventors: John McGiven, Laurence Howells, Lucy Duncombe, David Bundle, Satadru Sekhar Mandal, Susmita Sarkar
