title: Structural and serological studies on the O-antigen show that Citrobacter youngae PCM1505 must be classified to a new Citrobacter O-serogroup.
abstract: The O-polysaccharide obtained by mild acid hydrolysis of the lipopolysaccharide of Citrobacter youngae PCM1505 was studied by sugar and methylation analyses along with 1D and 2D (1)H and (13)C NMR spectroscopies. The following structure of the tetrasaccharide repeating unit of the polysaccharide was established: [Formula: see text]. Structural and serological data obtained earlier and in this work show that the strain studied is a candidate to a new Citrobacter O-serogroup.
