Abstract

The structure of the surface polysaccharide from a hypervirulent for mice Acinetobacter baumannii strain LAC-4 was studied. The polysaccharide was built of trisaccharide repeating units containing α-l-fucosamine, α-d-glucosamine, and α-8-epi-legionaminic acid. The structure interpretation was based mostly on NMR data. Polysaccharide was obtained using a procedure of LPS O-chain preparation, although whether it is an LPS O-chain or capsular polysaccharide remained unclear.
