    • The invention relates to novel interfering peptides having peptide sequence S with between 7 and 12 amino acids, originating from the peptide sequence of an antigenic protein of a micro-organism M, said sequence S being aligned with a peptide sequence S' with between 7 and 12 amino acids originating from the peptide sequence of a target protein of a micro-organism M' that is different from micro-organism M, provided that: sequences S and S' have at least 50% identity over their length of 7 to 12 amino acids and at least 4 identical or analogous contiguous amino acids; and their length is identical or they have 1 or 2 different amino acids distributed at one and/or the other end of said sequences. The invention also relates to the use thereof in a method for the in vitro immunoassay-based detection of the presence of a micro-organism M' or M in a biological sample in order to improve specificity.
    • 本发明涉及具有7至12个氨基酸的肽序列S的新型干扰肽,源自微生物M的抗原蛋白的肽序列,序列S与7'和 源于与微生物M不同的微生物M'的靶蛋白的肽序列的12个氨基酸,条件是:序列S和S'在其长度为7至12时具有至少50%的同一性 氨基酸和至少4个相同或类似的连续氨基酸; 并且它们的长度相同,或者它们在序列的一个和/或另一个末端分布有1或2个不同的氨基酸。 本发明还涉及用于体外免疫测定的生物样品中微生物M'或M存在的方法。
