A polysaccharide derivative with a repeating unit consisting of β-<small>D</small>-galactosyl, β-<small>D</small>-rhamnoosyl and β-<small>D</small>-glucosyl residues all linked (1→4), to the galactosyl residue of which is attached a β-<small>D</small>-galactosyl-(1→4)-<em>N</em>-acetyl-β-<small>D</small>-glucosaminyl disaccharide unit via a (1→3) linkage, while to the rhamnosyl residue is linked (1→3) an α-<small>D</small>-galactosyl residue, with all repeating units being linked (1→4). Desialylated capsular polysaccharide of <em>Streptococcus suis</em> serotype 2
