CAPSULATION OF PNEUMOCOCCUS WITH SOLUBLE C-LIKE (Cs) POLYSACCHARIDE
Capsulated mutants of pneumococcus producing a capsule of soluble polysaccharide related immunologically to the C or cell wall polysaccharide of pneumococcus have been isolated from several noncapsulated variants of this organism. The capsular material of these strains reacts with antisera both to homologous strains and to noncapsulated strains of pneumococcus and with human C-reactive protein....
متن کاملCapsulation of Pneumococcus with Soluble Cell Wall-like Polysaccharide
Methods are described for the separation of the C or cell wall polysaccharide from the C(s) or soluble C-like capsular polysaccharide of C(s) pneumococcal strains. Immunologic analysis has shown that both the C and C(s) polysaccharides of a variety of pneumococcal strains are heterogeneous and that the dissimilarities appear to reside in the mucopeptide portion of the molecule or in the region ...
متن کاملStudies on the Somatic C Polysaccharide of Pneumococcus
The capacity of the serum of rabbits following intradermal pneumococcus infections to precipitate in the presence of pneumococcus C polysaccharide has been studied during the resultant periods of active infection and during recovery. In rabbits infected with Type I, III, or VIII pneumococci, large hemorrhagic lesions are produced which frequently bring about death of the animals after a febrile...
متن کاملThe Capsular Polysaccharide of Pneumococcus Type Ix
The capsular polysaccharide of Type IX pneumococcus contains D-glucose, N-acetyl-D-glucosamine, and D-glucuronic acid. Complete hydrolysis is difficult. All of the N-acetylglucosamine is resistant to oxidation by periodate, but the other two sugars are degraded in part. Chemical and quantitative serological data are consistent with the linkage of two D-glucose residues 1 --> 4, as in maltose; o...
متن کاملThe Complement Fixation Reaction with Pneumococcus Capsular Polysaccharide
1. Complement is not fixed by immune aggregates resulting from the interaction of pneumococcus capsular polysaccharide and type-specific immune horse serum, although under proper conditions the substitution of immune rabbit serum gives positive results. 2. The negative results with immune horse serum are due to some poorly understood property of the specific antibodies rather than to some heter...
