摘要
Sialic acids, that are important constituents of animal tissue glycoconjugates, are also present in antigens of some bacteria strains. Capsular polysaccharides with sialic acid have been extensively studied whereas little is known on lipopolysaccharides which contain sialic acid. The susceptibility of Gram-negative strains with sialic acid-containing lipopolysaccharides to the bactericidal action or the sera of newborns was examined. The strains investigated showed variable sensitivity to the bactericidal action of normal cord serum.
