Structure of the capsular polysaccharide (CPS) from A. baumannii MAR21-2688 strain (classified as KL111 type) was established using 1H and 13C NMR spectroscopy, including two-dimensional homonuclear 1Н,1Н COSY, TOCSY, ROESY and heteronuclear 1Н,13C HSQC and HMBC experiments and chemical methods including component analyses and Smith degradation. The following structure of the branched hexasaccharide repeating K-unit was established
