Streptococcal Teichoic Acid
Teichoic acid-like material extracted by cold trichloroacetic acid from lyophilized whole cells of streptococci from groups A, D, E, 0, and T was shown to give a positive precipitin reaction with group antisera. Similar material from cells of groups B, C, F, G, H, K, L, M, N, P, Q, R, and S did not give a positive reaction with group antisera. The group A material also reacted with anti-E serum...
متن کاملNew group D streptococcal species.
BACKGROUND & OBJECTIVES The heterogeneity of group D streptococci led to the identification of various biotypes of Streptococcus equinus and Streptococcus bovis and to the description of new species. The objective of the present study was to improve the phenotypic delineation between species and to clarify their respective phylogenetic position. METHODS Physiological and genomic analyses were...
متن کاملCross-reactions of streptococcal group N teichoic acid in antipneumococcal horse sera of types VI, XIV, XVI, and XXVII.
The group antigen of Streptococcus lactis (group N) is an intracellular teichoic acid. It contains glycerophosphate and galactose phosphate, and the latter appears to form part, at least, of the immunological determinant reactive with group N antiserum (S. D. Elliott, Nature 200: 1184, 1963). Cross-reactions occur among teichoic acids, and we now record a series of crossprecipitations between t...
متن کاملEnzyme immunoassay for the detection of group A streptococcal antigen.
A competitive inhibition enzyme immunoassay for the detection of Streptococcus pyogenes directly from throat specimens or from solid bacteriological medium is described. Group A-specific polysaccharide adsorbed onto treated polystyrene beads, in conjunction with rabbit antibody to S. pyogenes, was used to determine the presence of the polysaccharide antigen. Inhibition values in excess of 65% w...
متن کاملImmunochemistry of the streptococcal group R cell wall polysaccharide antigen.
The group R streptococcal group antigen has been shown to be a polysaccharide located at the surface of the cell wall of the organism. The antigen was extracted from cell walls in 0.05 n HCl or 5% trichloracetic acid at 100 C, from whole cells at room temperature in 0.85% NaCl or 0.1 m acetate (pH 5.0), and by sonic oscillation. The antigen is largely destroyed when extracted from whole cells i...
