title: Electron microscopic visualization of extracellular polysaccharides on the cell wall of some streptococci.
abstract: The thickness of the acid polysaccharide capsule varied remarkably among the studied streptococci. In some strains, projections of the capsule and sloughing of the polysaccharide were observed in the medium.
