A polysaccharide derivative with a repeating unit consisting of α-<small>D</small>-mannosyl, α-<small>L</small>-rhamnosyl (acetylated on either O-2 or -3) and α-<small>D</small>-galactosyl residues linked sequentially (1→4) and (1→3), to the mannosyl residue is linked (1→3) an α-abequosyl residue (partially acetylated on O-2), while to the galactosyl residue is linked (1→4) or (1→6) an α-<small>D</small>-glucosyl residue, with all repeating units being linked (1→2). O-polysaccharide repeat from <em>Salmonella Typhimurium</em> (serogroup B).
