摘要: Electron microscopy of ruthenium red-stained ultrathin section strains Shigella dysenteriae type 1 grown in the Casamino Acids-yeast extract broth medium showed presence an extracellular slime layer. The appeared as a dense sheath covering bacteria. promoted hemagglutinating activity polysaccharide (SPS) isolated from cell-free culture supernatant or bacterial surface was less than 162,000 daltons size and immunochemically similar. SPS cross-reaction with lipopolysaccharide (LPS) antigen immunological tests; however, it also to be different LPS since did not contain 2-keto-3-deoxyoctonate, core sugar LPS. A pattern separation observed by silver staining SDS-polyacrylamide gels. From these data that either are contaminated each other is portion
