Studies of Streptococcal Cell Walls VII. Carbohydrate Composition of Group B Cell Walls

Studies of streptococcal cell walls. V. Amino acid composition of cell walls of virulent and avirlent group A hemolytic streptococci.

Investigations of the cellular components concerned with the antigenicity and virulence of group A streptococci indicate that the typespecific M protein is the antigen most consistently associated with virulence (Lancefield, 1940). The ability of these organisms to resist phagocytosis is, perhaps, the most important factor in conferring virulence. Wiley and Wilson (1956) have made an extensive ...

Glycans from Streptococcal Cell Walls

The cell wall of Streptococcus faecalis, strain N, has been found to contain two antigenic glycans, a diheteroglycan of glucose and galactose and a tetraheteroglycan of rhamnose, glucose, galactose, and N-acetylgalactosamine. The present report describes the isolation, purification, and structural and immunochemical characterization of the hitherto unknown diheteroglycan. A tentative structure ...

The Cell Walls of Group D Streptococci

Group D Types 1 and 26 cell walls and the corresponding type-specific carbohydrates, extracted from the walls by various means, contain rhamnose, glucose, galactose, N-acetylglucosamine, and N-acetylgalactosamine. Mucopeptide elements are also present in the walls and in enzymatically-extracted carbohydrates. Types 1 and 26 carbohydrates extracted by formamide contain no mucopeptide, but the se...
