title: [Antigenic polysaccharides of bacteria. 21. The structure of O-specific polysaccharide chains and serological specificity of lipopolysaccharides from 7 Pseudomonas aeruginosa immunotypes].
abstract: On mild acid degradation on lipopolysaccharides of seven Pseudomonas aeruginosa immunotypes, O-specific polysaccharides were obtained and their structures established. A peculiar feature of the polysaccharides is the presence of various, mostly acidic, mono- and diaminosugars, many of which have not previously been found in nature. The absence of serological cross-reactions (inhibition of passive haemagglutination) between lipopolysaccharides of seven immunotypes correlates with the absence of any common oligosaccharide fragments in their O-specific chains. The data obtained revealed structural and serological interrelations between O-antigens of seven immunotypes and P. aeruginosa O-serotypes, and showed that immunotypes 1 and 7 should be included into the serological classification scheme as individual O-serotypes.
