✦ Synopsis

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 neutral polymer isolated from the reference strain for serogroup O10, which cross-reacts strongly with O22. ----2)-alpha-L-Rhap-(1----2)-alpha-L-Rhap-(1----3)-alpha-L-+ ++Rhap-(1----3)-alpha- D-GlcpNAc-(1----

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-

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 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 Kle
