title: [Antigenic bacterial polysaccharides. Structure of O-specific polysaccharides from Pseudomonas cepacia serogroups C, I, O1, and O4].
abstract: Like some Pseudomonas cepacia serogroups studied earlier, serogroups C, I (Nakamura), O1 and O4 (Heidt) are characterized by the presence of at least two structurally different O-antigenic polysaccharide chains in cell-wall lipopolysaccharides. On the basis of acid hydrolysis, methylation, 1H- and 13C-NMR spectroscopy, including computer-assisted 13C-NMR-based analysis, the complete structures of the predominant polysaccharides of serogroups I (I), C and O4 (III) and the minor polysaccharides of serogroups I (II) and O1 (V) were established, and the structure of the predominant polysaccharide of serogroup O1 (IV) established earlier (Cox A. D., Wilkinson S. G.@Carbohydr. Res. 1990. V. 195. No 2. P. 295-301) was confirmed.
