In continuation of our studies of the surface polysaccharides produced by reference strains of Serratia marcescens, we have isolated the lipopolysaccharide of the 015 strain C.D.C. 4523-60 (yield, 18% of the cell walls). The neutral monosaccharide composition (expressed as percentages of the total p

โฆ Synopsis
Both a neutral and an acidic polymer have been isolated from a lipopolysaccharide extract of Serratia marcescens strain S3255. The neutral polymer is a linear mannan with the repeating unit shown. The same repeating unit has been described for the O-specific polymers from Escherichia coli O8 and Klebsiella O5.

In addition to a neutral glycan, lipopolysaccharide extracts from the reference strain for Serratia marcescens serogroup O22 contain an acidic polymer which probably defines the serogroup and is of microcapsular origin. The polymer is doubly branched with a heptasaccharide repeating unit and a galac
Both a neutral and an acidic polymer have been isolated from a lipopolysaccharide extract of the reference strain for Serratia marcescens serogroup O22. The neutral polymer has a linear structure with the repeating unit shown. The same tetrasaccharide unit also forms the backbone of the branched neu
The lipopolysaccharide extract from the cell wall of the reference strain for Serratia marcescens serogroup O18 contained, in addition to a neutral glycan characterised previously, an acidic glycan. Acidity was contributed both by D-glucuronic acid and by 4-O-[(R)-1-carboxyethyl]-D-glucose (4-O-Lac-
The current scheme for typing strains of Serratia marcescens by their heat-stable antigens is undergoing major reconstruction as a result of chemical studies allied with serological reappraisal . L\* Evidence has accumulated that many of the existing 24 0 serogroups are actually defined by acidic,
