Acinetobacter species are free-living, non-fermentative, Gram-negative bacteria, some of which have become important as opportunistic pathogens, often characterised by multiple drug resistance [1]. Of the various genospecies currently recognised, Acinetobacter baumannii is the one most commonly asso

β¦ Synopsis
A polysaccharide containing D-galactose, o-glucose, and 2-acetamido-2-deoxy-D-galactose was obtained from an aqueous phenol extract of isolated cell walls from Acinetobacter baumannii strain 214. By means of NMR studies and chemical degradations, the repeating unit of the polymer was identified as a branched trisaccharide of the structure shown.
