title: Lipopolysaccharides of flagellated and non-flagellated Proteus vulgaris strains.
abstract: Lipopolysaccharides from two strains of Proteus vulgaris were analyzed. One strain (08) was motile, giving swarming growth on solid media and the other (04)--non-flagellated, not able to swarm. Both lipopolysaccharides appeared to be heterogeneous and were separated into two fractions each. Yield, chemical composition and SDS-polyacrylamide gel electrophoresis showed differences between fractions in percentage content of 0-specific and R-core polysaccharides. Relation between ability to swarming growth of Proteus strains and heterogeneity of their lipopolysaccharides is also discussed.
