The immunochemistry of Salmonella chemotype VI O-antigens. The structure of oligosaccharides from Salmonella group U (o 43) lipopolysaccharides.
1. A series of oligosaccharides was isolated from Salmonella milwaukee lipopolysaccharide by partial acid hydrolysis. 2. Structural studies on these oligosaccharides indicated that the O-specific side chain of this lipopolysaccharide has a repeating pentasaccharide unit that is probably alpha-d-galactosyl-(1-->3)-beta-d-galactosyl- (1-->3)-N-acetylgalactosaminyl-(1-->3)-N-acetyl- d-glucosaminyl...
متن کاملIdentification of Salmonella O antigens by coagglutination.
This study concerns the preparation of reagents for identifying the somatic O antigens of Salmonella enteritidis. Coagglutination reagents (COAGs) with antibody fixed to killed and stabilized protein A-bearing staphylococci were prepared with antisera which were used for identifying the somatic O antigens of S. enteritidis by the slide agglutination test. The reactions of the COAGs were compare...
متن کاملA group of Escherichia coli and Salmonella enterica O antigens sharing a common backbone structure.
The O-antigen moiety of the LPS is one of the most variable cell surface components of the Gram-negative bacterial outer membrane. Variation is due to the presence of different sugars and sugar linkages. Here, it is reported that a group of Escherichia coli O serogroups (O17, O44, O73, O77 and O106), and the Salmonella enterica serogroup O : 6,14 (H), share a common four-sugar backbone O-subuni...
متن کاملGlycosyltransferase functions of E. coli O-antigens.
ECODAB (the E. coli O-antigen database) has been expanded to include information about glycosyltransferases (GTs) involved in the assembly of the O-antigen polysaccharide. Similarity searches have been performed to be able to determine GT functions that have not been reported prior to this work. In addition to suggesting the function of 179 GTs, the approach leads to the prediction of part of t...
