The Structure of the Lipopolysaccharide O-chain (M Antigen) and Polysaccharide B Produced by Brucella Melitensis 16M

FEBS Lett. 1987 Jun 1;216(2):261-4. doi: 10.1016/0014-5793(87)80702-0.


The surface M antigen of Brucella species has been identified as the lipopolysaccharide O-polysaccharide component composed of a repeating pentasaccharide unit containing a sequence of one 1,3- and four 1,2-linked, 4,6-dideoxy-4-formamido-alpha-D-mannopyranosyl units. A neutral polysaccharide produced by Brucella species and referred to as polysaccharide B (poly B) has been identified as a family of circular 1,2-linked polymers of beta-D-glucopyranosyl units ranging in ring size from 17 to 24 glucosyl units.
