The structure of the O-polysaccharide of Proteus mirabilis CCUG 10705 (OF) was determined by chemical analyses along with one- and two-dimensional (1)H and (13)C NMR spectroscopy. The polysaccharide was found to contain an amide of D-galacturonic acid with L-alanine and based on the uniqueness of the O-polysaccharide structure and serological data, it was suggested to classify P. mirabilis OF into a new separate Proteus serogroup, O74. A weak cross-reactivity of P. mirabilis OF and P. mirabilis O5 was observed and accounted for by a similarity of their O-repeating units. The following structure of the polysaccharide of P. mirabilis OF was established: [chemical structure: see text]
通过化学分析以及一维和二维（1）H 和（13）C NMR 光谱法确定了奇异变形杆菌 CCUG 10705（OF）的 O-多糖结构。发现该多糖含有 D-半乳糖醛酸与 L-丙氨酸的酰胺，基于 O-多糖结构的独特性和血清学数据，建议将奇异变形杆菌 OF 分类为一个新的独立变形杆菌血清群，O74。观察到奇异变形杆菌 OF 与奇异变形杆菌 O5 有弱交叉反应，这是由于它们的 O-重复单元相似所致。确定了奇异变形杆菌 OF 多糖的以下结构：[化学结构：见正文]
