    • The present invention relates to immunogenic compositions comprising isolated Clostridium difficile CDTb and/or CDTa protein. In particular the isolated Clostridium difficile CDTb protein is suitably a truncated CDTb protein comprising the receptor binding domain or a mutated CDTb protein incapable of binding to CDTa, and the isolated Clostridium difficile CDTa protein is suitably a truncated CDTa protein which does not comprise the C-terminal domain. In particular the invention also relates to fusion proteins comprising a CDTa protein and a CDTb protein and also fusion proteins between an isolated Clostridium difficile toxin A protein and/or an isolated Clostridium difficile toxin B protein fused to a CDTb protein. The invention further relates to compositions comprising fragments or variants of SEQ ID NO:3, SEQ ID NO:7, SEQ ID NO:16, SEQ ID NO:9, SEQ ID NO:51, SEQ ID NO:34, SEQ ID NO:36, SEQ ID NO:50, SEQ ID NO:14, SEQ ID NO:15, SEQ ID NO:46, SEQ ID NO:48, SEQ ID NO:52, SEQ ID NO:54, SEQ ID NO:40, SEQ ID NO:41 or SEQ ID NO:42 or SEQ ID NO:43 or SEQ ID NO:44 or SEQ ID NO:45.
    • 本发明涉及包含分离的难辨梭状芽胞杆菌CDTb和/或CDTa蛋白的免疫原性组合物。 特别地,分离的艰难梭菌CDTb蛋白质合适地是包含受体结合结构域的截短的CDTb蛋白或不能结合CDTa的突变的CDTb蛋白,分离的艰难梭菌CDTa蛋白合适地是不包含C-末端的截短的CDTa蛋白, 终端域。 特别地,本发明还涉及包含CDTa蛋白和CDTb蛋白的融合蛋白,以及与CDTb蛋白融合的分离的艰难梭菌毒素A蛋白和/或分离的艰难梭菌毒素B蛋白之间的融合蛋白。 本发明还涉及包含SEQ ID NO:3,SEQ ID NO:7,SEQ ID NO:16,SEQ ID NO:9,SEQ ID NO:51,SEQ ID NO:34,SEQ ID NO :36,SEQ ID NO:50,SEQ ID NO:14,SEQ ID NO:15,SEQ ID NO:46,SEQ ID NO:48,SEQ ID NO:52,SEQ ID NO:54,SEQ ID NO:40 ,SEQ ID NO:41或SEQ ID NO:42或SEQ ID NO:43或SEQ ID NO:44或SEQ ID NO:45。
