Serotypes 3, 4, and 8 of Ureaplasma urealyticum were found to contain lipoglycans. Although the ratios of their components differed, all contained neutral sugars, fatty acids, glycerol, and phosphorus. All three became labeled when the organisms were cultivated in the presence of [14C]glucose, [14C]palmitic or [14C]oleic acids, and inorganic 32P. Only neutral sugars were found, and these consisted of mannose, glucose, and galactose. Hot phenol extracts of uninoculated and supernatant culture media contained polymeric carbohydrate, but this differed in composition from ureaplasmal lipoglycans and did not become radiolabeled. Since lipoglycans contained phosphorus but no amino sugars, they could be separated from contaminating polysaccharides by anion exchange chromatography.
解脲脲原体的血清型3、4和8被发现含有脂聚糖。尽管它们各成分的比例不同,但都含有中性糖、脂肪酸、甘油和磷。当这些微生物在[14C]葡萄糖、[14C]棕榈酸或[14C]油酸以及无机32P存在的情况下培养时,所有三种血清型都会被标记。只发现了中性糖,这些中性糖由甘露糖、葡萄糖和半乳糖组成。未接种的和上清培养基的热酚提取物含有聚合碳水化合物,但这种聚合碳水化合物的组成与脲原体脂聚糖不同,并且不会被放射性标记。由于脂聚糖含有磷但不含氨基糖,因此可以通过阴离子交换色谱法将它们与污染的多糖分离。
