Abstract

Lipopolysaccharides (LPS) of the same chemotype isolated from seven strains of Fusobacterium nucleatum were examined by indirect haemagglutination and inhibition of haemagglutination in unabsorbed and absorbed antisera. Four common major antigenic specificities were detected, and two of the LPS examined contained antigenic specificities not shared with any of the other LPS. In addition, a few weak cross-reactions were observed, also with some LPS of other chemotypes.

摘要

通过间接血凝试验以及未吸收和吸收抗血清中的血凝抑制试验，对从七株具核梭杆菌中分离出的相同化学型的脂多糖（LPS）进行了检测。检测到四种常见的主要抗原特异性，并且所检测的两种LPS含有与其他任何LPS都不共有的抗原特异性。此外，还观察到一些微弱的交叉反应，其他化学型的一些LPS也有此现象。
