Structural and serological characterisation of the O-antigenic polysaccharide of the lipopolysaccharide from Acinetobacter strain 96 (DNA group 11)Institute for Biological Sciences, NRCC, Ottawa, Ontario, Canada

The structure of the O-antigen was determined by compositional analysis and NMR spectroscopy of the polysaccharide as: A monoclonal antibody obtained after immunization of mice with heat-killed bacteria of Acinetobacter strain 96 was shown to bind to the O-antigen and did not cross-react with any Acinetobacter O-antigen of known structure.
