Primary structure of the Escherichia coli serotype K30 capsular polysaccharide.
Methylation, 1H nuclear magnetic resonance, and bacteriophage degradation results indicate that the Escherichia coli serotype K30 capsular polysaccharide consists of leads to 2)-alpha-D-Manp-(1 leads to 3)-beta-D-Galp-(1 leads to chains carrying beta-D-GlcUAp-(1 leads to 3)-alpha-D-Galp-(1 leads to branches at position 3 of the mannoses.
متن کاملPrimary structure of the Escherichia coli serotype K42 capsular polysaccharide and its serological identity with the Klebsiella K63 polysaccharide.
The Escherichia coli K42 capsular polysaccharide consists of leads to 3)-alpha-D-Galp-(1 leads to 3)-alpha-D-GalUAp-(1 leads to 3)-alpha-L-Fucp-(1 leads to repeating units. The E. coli K42 and Klebsiella K63 antigens are serologically identical.
متن کاملPurification of capsular polysaccharide produced by Streptococcus pneumoniae serotype 19A.
Streptococcus pneumoniae is a major cause of invasive infection in young infants and older adults. There are currently 90 capsular serotypes identified and 23 serotypes (1, 2, 3, 4, 5, 6B, 7F, 8, 9N, 9V, 10A, 11A, 12F, 14, 15B, 17F, 18C, 19F, 19A, 20, 22F, 23F, and 33F) are responsible for about 90% of invasive disease. Among the more than 90 different S. pneumoniae serotypes, serotype 19A is g...
متن کاملMOLECULAR CHARACTERIZATION AND OPTIMIZATION OF VI-CAPSULAR POLYSACCHARIDE OF SALMONELLA TYPHI TY6S PRODUCTION IN BIOREACTOR
The role of Vi-capsular polysaccharide (Vi-CPS) in human immunity against infection caused by Salmonella typhi is well known. The downstream process of purification generally causes depolymerization of Vi-CPS to a nonimmunogenic low molecular weight form. In the present study, a standard strain of Sal. typhi Ty6s was grown under submerge cultural conditions in a pilot-plant scale of 90 Liter fe...
