نویسندگان
چکیده
The specific capsular polysaccharide of type 46 Streptococcus pneumoniae (American type 73) was isolated in pure form and shown to be a high-molecular-weight, glycosidically linked polymer composed of d-galactose (2 mol), N-acetyl-d-glucosamine (1 mol), N-acetyl-d-galactosamine (1 mol), and N-acetyl-l-fucosamine (1 mol).

Specific capsular polysaccharide of type 45 Streptococcus pneumoniae (American type 72).
The specific capsular polysaccharide of type 45 Streptococcus pneumoniae was isolated in pure form by chemical and chromatographic methods and found to be a high-molecular-weight, glycosidically linked polymer of a hexasaccharide repeating unit composed of D-galactose (2 mol), L-rhamnose (1 mol), N-acetyl-D-glucosamine (1 mol), N-acetyl-D-galactosamine (1 mol), N-acetyl-L-fucosamine (1 mol), an...
متن کاملStructurally identical capsular polysaccharide expressed by intact group B streptococcus versus Streptococcus pneumoniae elicits distinct murine polysaccharide-specific IgG responses in vivo.
We previously reported distinct differences in the murine in vivo Ig polysaccharide (PS)-specific responses to intact Streptococcus pneumoniae compared with responses to Neisseria meningitidis and that in each case, the bacterial subcapsular domain markedly influences the Ig response to the associated PS. In light of potentially unique contributions of biochemically distinct capsular PS and/or ...
متن کاملCharacterization of the cassette containing genes for type 3 capsular polysaccharide biosynthesis in Streptococcus pneumoniae
The capsular polysaccharide is the major virulence factor of Streptococcus pneumoniae. Previously, we identified and cloned a region from the S. pneumoniae chromosome specific for the production of type 3 capsular polysaccharide. Now, by sequencing the region and characterizing mutations genetically and in an in vitro capsule synthesis assay, we have assigned putative functions to the products ...
متن کاملFilamentous capsulated streptococci from the human respiratory tract. I. Antigenic attributes of provisional capsular type 83 and its relationship to streptococci of so-called group M.
Two immunologically reactive polysaccharides have been isolated from the cell walls and from culture filtrates of a filamentous alpha-hemolytic streptococcus provisionally designated capsular type 83. Both polysaccharides were purified by diethylaminoethyl-cellulose chromatography. Analysis indicates that the capsular polysaccharide consists of galactose and phosphorus, whereas the cell wall po...
متن کاملDefinition of a bacterial virulence factor: sialylation of the group B streptococcal capsule.
Sialylation of bacterial capsules has been proposed as an important virulence factor for several species of encapsulated pathogens, including group B Streptococcus. We have constructed a transposon mutant strain of type III group B Streptococcus that expresses a capsular polysaccharide differing from the wild type only in that the mutant strain's capsule lacks sialic acid. The mutant polysaccha...
