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.
