  The invention relates to a synthetic oligosaccharide representing part of the repeating unit of the Clostridium difficile glycopolymer PS-I and having the sequence of the pentasaccharide a-L-Rhap-(1→3)-β-D-Glcp-(1→4)-[a-L-Rhap-(1→3]-a-D-Glcp-(1→2)-a-D-Glcp or a synthetic fragment or derivative thereof. Preferably, the claimed synthetic oligosaccharide bears at least one linker L for conjugation to a carrier protein or for immobilization on a surface. Further aspects of the invention relate to advantageous methods for synthesizing said synthetic oligosaccharide and oligosaccharide-protein conjugate as well as to uses thereof, in particular as vaccines and diagnostic tools.

  本发明涉及一种合成寡糖，其代表Clostridium difficile糖聚合物PS-I重复单元的一部分，并具有五糖核苷酸序列a-L-Rhap-(1→3)-β-D-Glcp-(1→4)-[a-L-Rhap-(1→3]-a-D-Glcp-(1→2)-a-D-Glcp或其合成片段或衍生物。优选地，所述合成寡糖至少带有一种连接物L，用于与载体蛋白质结合或固定在表面上。本发明的其他方面涉及有利的方法，用于合成所述合成寡糖和寡糖-蛋白质结合物，以及其用途，特别是作为疫苗和诊断工具。
