A complete view of the genetic diversity of the Escherichia coli O-antigen biosynthesis gene cluster
The O antigen constitutes the outermost part of the lipopolysaccharide layer in Gram-negative bacteria. The chemical composition and structure of the O antigen show high levels of variation even within a single species revealing itself as serological diversity. Here, we present a complete sequence set for the O-antigen biosynthesis gene clusters (O-AGCs) from all 184 recognized Escherichia coli...
متن کاملOrganization of Escherichia coli O157 O antigen gene cluster and identification of its specific genes.
The O157:H7 clone of Escherichia coli, which causes major, often prolonged outbreaks of gastroenteritis with hemolytic-uremic syndrome (HUS) such as those in Japan, Scotland, and the United States recently, is thought to be resident normally in cattle or other domestic animals. This clone is of major significance for public health and the food industry. We have developed a fast method for seque...
متن کاملStructure and gene cluster of the O-antigen of Escherichia coli O36.
The O-polysaccharide (O-antigen) of Escherichia coli O36 was isolated from the lipopolysaccharide and studied by sugar analyses and Smith degradation along with (1)H and (13)C NMR spectroscopy. The following structure of the branched pentasaccharide repeating unit was established, which is unique among the known structures of bacterial polysaccharides: The O-antigen gene cluster of E. coli O36 ...
