Antigenic polysaccharide specific to Brucella abortus and Yersinia enterocolitica serotype 0:9

Abstract

The antigenic O-chain polysaccharides from Brucella abortus and Yersinia enterocolitica serotype 0:9 have similar structure, i.e. 1-2 linked 4,6-dideoxy-4-formamido-.alpha.-D-mannopyranosyl units. The antigen is more readily isolated from the Yersinia and may be chemically modified to have a hydrophobic moiety attached thereto. The antigen can be adsorbed or coupled to carriers suitable for immunoassay use such as ELISA and RIA. A monoclonal antibody capable of specifically binding to B. abortus and Y. enterocolitica, has been produced. Assay procedures and kits therefor, are described.
