Structural studies have been carried out on the O‐specific polysaccharide from the lipopolysaccharide of the reference strain (CDC 1604–55) for serogroup O8 of Serratia marcescens . The polymer has a branched, tetrasaccharide repeating unit of d ‐galactose (Gal), d ‐glucose (Glc), and 2‐acetamido‐2‐deoxy‐ d ‐glucose (GlcNAc) with the following structure:The anomeric configuration assigned to the glucose residue differs from that (β) previously proposed [Tarcasy, L., Wang, C. S., Li, S.‐C. and Alaupovic, P. (1973) Biochemistry 12 , 1948–1955]. The structure of the O8 polymer is identical with that of one of two polymers present in the cell envelope of a strain (CDC 1783‐57) of S. marcescens O14.
