Composition of the lipopolysaccharide of Neisseria gonorrhoeae.

Abstract

Analysis of glycose and fatty acid content of lipopolysaccharide extracted from 38 strains of Neisseria gonorrhoeae indicated that glycoses common to colonial types 1 to 5 were glucose, mannose, and galactose, N-acetylneuraminic acid, 2-keto-3-deoxyoctulosonic acid (KDO), glucosamine, and galactosamine were also invariably present. Virulent colonial types 1 and 2 contained no rhamnose, in contrast to avirulent types 3 to 5 and several strains of the nonpathogenic species N. sicca and N. lactamica. Fucose, characteristic of these nonpathogenic species, was not present in the gonococci. Variation in the concentration of individual glycoses in different strains was also noted. Mannose-KDO, galactose-KDO, and glucose-KDO ratios of virulent gonococci exceeded those of avirulent organisms, except that the correlation for glucose was not quite so striking. This relationship was not found in N. sicca and N. lactamica strains. Fatty acid analyses of lipid A from gonococci showed that 10-, 12-, 14-, 16-, and 18-carbon acids, as well as 3-hydroxytetradecanoic acid, were present, but differences in concentration between colonial types, although evident in some cases, appeared less significant than glycose content.
