Characterization of lipopolysaccharides from Pseudomonas syringae (serogroup II)
Abstract:
Lipopolysaccharides (LPS) from the strains of Pseudomonas syringae pv.syringae 90a, 435, pv. atrofaciens K-1025, pv. morsprunorum CF-4 referred by Pastushenko and Simonovich (1979) to serogroup II have been studied. The strains were shown to be heterogeneous by chemical composition of core and lipid A and structure of O-specific polysaccharide. The preparations heterogeneity in serological cross reactions were also detected. O-specific polysaccharides of the strains having similar structures were not identical in serological tests. The assumption on the lipid A role in serogrouping of P. syringae strains has been advanced.
