  • Title: [Chemotypes of "Shigella flexneri" R mutants and related phage receptors. I. -- Chemical study of the lipopolysaccharides (author's transl)].
    Author: Hannecart-Pokorni E, Godard C, Beumer J.
    Journal: Ann Microbiol (Paris); 1976 Jul; 127(1):3-14. PubMed ID: 798513.
    Abstract:
    The F6R rough mutants isolated from Shigella flexneri F6S, serotype 5b, and the FH rough mutants, derived from other serotypes of S. flexneri, were chemotyped according to the chemical analysis of their lipopolysaccharides. Further, the following stages of lipopolysaccharide core biosynthesis in S. flexneri have been established: --(KDO)3--heptose--heptose--glucose--galactose; the last three stages are: either --glucose--glucosamine--glucose, or --glucosamine--glucose--glucose. The results of the chemical study of the R lipopolysaccharides are compatible with the assumption of the existence of a similar core in all considered S. flexneri serotypes.
