    Abstract: There is provided an epsilon toxin epitope polypeptide comprising a sequence of at least 10 contiguous amino acids from SEQ ID NO:3, the sequence comprising a mutation of at least one tyrosine residue compared to the equivalent sequence in SEQ ID NO:3, the polypeptide being capable of binding an antibody which binds to SEQ ID NO:5 and having reduced toxicity compared with the toxicity of SEQ ID NO:5. The polypeptide is useful in a method of vaccinating a subject against developing a disease caused by Clostridium perfringens and/or caused by (or associated with the presence of) active epsilon toxin.

    Abstract translation: 提供了包含SEQ ID NO:3的至少10个连续氨基酸的序列的ε-毒素表位多肽,所述序列包含与SEQ ID NO:3中的等同序列相比至少一个酪氨酸残基的突变,所述多肽 能够结合与SEQ ID NO:5结合的抗体,并且与SEQ ID NO:5的毒性相比具有降低的毒性。 该多肽可用于接种受试者以发展由产气荚膜梭菌引起的疾病和/或由活动性ε毒素(或与其存在)引起的疾病的疫苗接种的方法。
