A polysaccharide containing D-GalNAc, D-Glc and 4-acetamido-4,6-dideoxy-D-glucose (Qui4NAc) was isolated from the phenol-soluble lipopolysaccharide originating from Acinetobacter baumannii strain 9. The structure of the repeating unit was shown by means of monosaccharide analyses, Smith-degradation, partial acid hydrolysis, mass spectrometry, and NMR spectroscopy to be a branched pentasaccharide, in which the tetrasaccharide backbone is built from amino sugars only. [structure: see text] The polysaccharide was identified by serological and western blot analyses as the O-antigen of the lipopolysaccharide.
从鲍曼不动杆菌9型菌株的酚溶性脂多糖中分离出一种含有D-氨基半乳糖、D-葡萄糖和4-乙酰氨基-4,6-二脱氧-D-葡萄糖（Qui4NAc）的多糖。通过单糖分析、史密斯降解、部分酸水解、质谱和核磁共振光谱等方法表明，重复单元的结构是一种支链五糖，其中四糖主链仅由氨基糖构成。[结构：见正文] 通过血清学和蛋白质印迹分析确定该多糖为脂多糖的O抗原。
