Cell-wall lipopolysaccharide of the urinary-tract-infective Escherichia coli 04:K12:H-. Structure of the polysaccharide chain.


The O-specific polysaccharide moiety (04 polysaccharide) of the 04 antigen (lipopolysaccharide) from Escherichia coli 04:K12:H- was isolated in pure form by degradation of the lipopolysaccharide and chromatography on Sephadex G-50. The primary structure of the 04 polysaccharide was elucidated by composition, Smith degradation, nuclear magnetic resonance… (More)
