Biosynthesis of the O antigen from Citrobacter 139.
The biosynthesis of the O antigen of Citrobacter 139 (Escherichia coli 3 Zurich 4,5,12:z(20)) was shown to proceed through a series of lipid-linked intermediates, similar to those involved in O-antigen synthesis in Salmonella. Galactose was the first sugar incorporated, followed by rhamnose and mannose. Abequose was incorporated from cytidine diphosphate (CDP)-abequose only when all three of th...
متن کاملAntigenic scheme of Citrobacter koseri.
An antigenic scheme, based on the determination of 17 somatic and 9 flagellar antigens, is proposed for Citrobacter koseri. Seven of the flagellar antigens constituted the specific phase (a through g), and the others (1 and 2) were nonspecific. Of the 238 theoretically possible serotypes, 48 were identified among 680 cultures examined.
متن کاملBiochemical identification of Citrobacter species defined by DNA hybridization and description of Citrobacter gillenii sp. nov. (formerly Citrobacter genomospecies 10) and Citrobacter murliniae sp. nov. (formerly Citrobacter genomospecies 11).
Recent work describing six named species and two unnamed genomospecies within Citrobacter has enlarged the genus to 11 species. DNA relatedness and phenotypic tests were used to determine how well these species can be identified. One hundred thirty-six strains were identified to species level by DNA relatedness and then identified phenotypically in a blinded fashion. By using conventional tests...
متن کاملOn the antigenic relationships of certain Citrobacter and Hafnia cultures.
The biochemical and serological characters of 36 unclassified cultures are described, and according to these characters the organisms belong to the genera Citrobacter, Aerobacter and Hafnia. While studying the antigenic relationships of the 0 antigens the known antigenic relationship between some serotypes of Citrobacter and Salmonella was confirmed; new antigenic relationships with s. locarno,...
متن کاملAddendum to: ``Structure and serological properties of O-speci¢c polysaccharide from Citrobacter freundii possessing cross-reactivity with Escherichia coli O157:H7''
The article described an interpretation for the cross-reactivity between Citrobacter freundii OCU 158 and Escherichia coli O157:H7, which is due to apparently identical O-speci¢c polysaccharides in both strains. Brie£y, we investigated the structure of O-speci¢c polysaccharides by gas chromatography/mass spectrometry (GC/MS) and nuclear magnetic resonance (NMR) analyses in comparison with the d...
