Structural heterogeneity of the lipopolysaccharides of the Neisseriaceae
Abstract:
Lipopolysaccharides from 5 different genera of the Neisseriaceae were analyzed on sodium dodecylsulfate-polyacrylamide gel electrophoresis, and visualized by silver staining. Significant heterogeneity in the banding patterns was observed with some of the strains producing only low molecular mass molecules and others producing O-repeating units. All genera examined except Branhamella contained strains that were able to produce an O-repeating side chain on their lipopolysaccharides. The ability to produce the repeating subunit did not correlate with the presence of plasmids.
