Abstract

O-Polysaccharide was obtained by mild acid degradation of the lipopolysaccharide of Providencia alcalifaciens O45:H25 and studied by sugar analysis, Smith degradation, and (1)H and (13)C NMR spectroscopy. The following structure of the pentasaccharide repeat of the O-polysaccharide was established: [structure: see text]. The O-antigen gene cluster of P. alcalifaciens O45 was sequenced and found to be in full agreement with the O-polysaccharide structure established.

Keywords: Bacterial polysaccharide structure; Lipopolysaccharide; O-Antigen gene cluster; Providencia alcalifaciens.
