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.
对一株对小鼠具有高毒力的鲍曼不动杆菌LAC-4菌株的表面多糖结构进行了研究。该多糖由含有α-L-岩藻糖胺、α-D-葡糖胺和α-8-表军团氨糖酸的三糖重复单元构成。结构解析主要基于核磁共振数据。多糖是采用脂多糖O抗原链制备方法获得的，不过它究竟是脂多糖O抗原链还是荚膜多糖仍不清楚。
