Vinogradov E, MacLean L, Xu HH, Chen W
The structure of the polysaccharide isolated from Acinetobacter baumannii strain LAC-4
Carbohydrate Research 390 (2014)
42-45
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.

Surface polysaccharides from Acinetobacter baumannii: Structures and syntheses
Carbohydrate Research 418 (2015)
29-43
The emergence of multidrug-resistance Acinetobacter baumannii requires novel approaches for prevention, treatment and diagnosis. The structures of surface polysaccharides from A. baumannii are valuable tools to understand pathogenesis, virulence and immunogenicity. The synthesis of bacterial mono- or polysaccharides may result in novel probes to become important therapeutic options in the fight against A. baumannii. This report exemplifies the relevance of glycochemistry for the development of new antibiotics.
