title: O-antigen structure and gene clusters of Escherichia coli O51 and Salmonellaenterica O57; another instance of identical O-antigens in the two species.
abstract: The O-polysaccharides were released by mild acid hydrolysis from the lipopolysaccharides of Escherichia coli O51 and Salmonella enterica O57 and found to possess the same structure, which was established by sugar analysis and 1D and 2D NMR spectroscopy: [formula in text]. The O-antigen gene clusters of E. coli O51 and S. enterica O57 were sequenced and found to contain the same genes with a high-level similarity. All genes expected for the synthesis of the O-antigen were identified based on their similarity to genes from available databases.
