    • The present invention relates to fusion proteins comprising fragments from toxin A and/or toxin B of Clostridium difficile, in particular the invention relates to proteins comprising a first fragment and a second fragment, wherein
      [0205] the first fragment is a toxin A repeating domain fragment;
      [0206] the second fragment is a toxin B repeating domain fragment;
      [0207] the first fragment has a first proximal end;
      [0208] the second fragment has a second proximal end; and wherein the first fragment and the second fragment are adjacent to one another and wherein the polypeptide elicits antibodies that neutralize toxin A or toxin B or both. The invention further relates to compositions comprising fragments or variants of SEQ ID NO:10, SEQ ID NO:11, SEQ ID NO:12, SEQ ID NO:13, SEQ ID NO:14, SEQ ID NO:15, SEQ ID NO:16, SEQ ID NO:17, SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:28, SEQ ID NO:29, SEQ ID NO:30, SEQ ID NO:31, SEQ ID NO:32, SEQ ID NO:33 or SEQ ID NO:34 or SEQ ID NO:35.
    • 本发明涉及包含来自艰难梭菌的毒素A和/或毒素B的片段的融合蛋白,特别地,本发明涉及包含第一片段和第二片段的蛋白质,其中第一片段是毒素A重复结构域 分段; [0206]第二片段是毒素B重复结构域片段; [0207]第一片段具有第一近端; [0208]第二片段具有第二近端; 并且其中所述第一片段和所述第二片段彼此相邻,并且其中所述多肽引发中和毒素A或毒素B或两者的抗体。 本发明还涉及包含SEQ ID NO:10,SEQ ID NO:11,SEQ ID NO:12,SEQ ID NO:13,SEQ ID NO:14,SEQ ID NO:15,SEQ ID NO:10的片段或变体的组合物 :16,SEQ ID NO:17,SEQ ID NO:18,SEQ ID NO:19,SEQ ID NO:28,SEQ ID NO:29,SEQ ID NO:30,SEQ ID NO:31,SEQ ID NO:32 ,SEQ ID NO:33或SEQ ID NO:34或SEQ ID NO:35。
