O-antigenic corss-reactivity in Fusobacterium nucleatum: chemotype V lipopolysaccharides.

Abstract

nucleatum lipopolysaccharides (LPS) of chemotype V were examined for cross-reactivity by indirect haemagglutination in non-absorbed and absorbed antisera. At least three O-antigenic specificities were detected in LPS of five strains. There was a slight cross-reactivity between the LPS of chemotype V and those of chemotype II.
