    • This invention relates to conjugates of the O-specific polysaccharide of E. coli O157 with a carrier, and compositions thereof, and to methods of using of using of these conjugates and/or compositions thereof for eliciting an immunogenic response in mammals, including responses which provide protection against, or reduce the severity of, bacterial infections. More particularly it relates to the use of polysaccharides containing the tetrasaccharide repeat unit: (→3)-α-DGalpNAc-(1→2)-α-D-PerpNAc-(1→3) -α-L-Fucp-(1→4)-β-D-Glcp-(1→), and conjugates thereof, to induce serum antibodies having bactericidal (killing) activity against hemolytic-uremic syndrome (HUS) causing E. coli, in particular E. coli O157. The conjugates, and compositions thereof, are useful as vaccines to induce serum antibodies which have bactericidal or bacteriostatic activity against E. coli, in particular E. coli O157, and are useful to prevent and/or treat illnesses caused by E. coli O157.The invention further relates to the antibodies which immunoreact with the O-specific polysaccharide of E. coli O157 and/or the carrier, that are induced by these conjugates and/or compositions thereof. The invention also relates to methods and kits using one or more of the polysaccharides, conjugates or antibodies described above.
    • 本发明涉及大肠杆菌O157的O-特异性多糖与载体及其组合物的缀合物,以及这些缀合物和/或其组合物在哺乳动物中引发免疫原性应答的方法,包括提供保护的应答 反对或减轻细菌感染的严重性。 更具体地说,涉及使用含有四糖重复单元的多糖:(→3)-alpha-DGalpNAc-(1-> 2)-alpha-D-PerpNAc-(1-> 3)-alpha-L-Fucp - (1-> 4)-β-D-Glcp-(1->)及其缀合物,以诱导对引起大肠杆菌的溶血性尿毒综合征(HUS)具有杀菌(杀伤)活性的血清抗体,特别是E 大肠杆菌O157。 缀合物及其组合物可用作诱导对大肠杆菌特别是大肠杆菌O157具有杀菌或抑菌活性的血清抗体的疫苗,并且可用于预防和/或治疗由大肠杆菌O157引起的疾病。 本发明还涉及与这些缀合物和/或其组合物诱导的大肠杆菌O157和/或载体的O-特异性多糖免疫反应的抗体。 本发明还涉及使用上述一种或多种多糖,缀合物或抗体的方法和试剂盒。
