摘要

对两株钩端螺旋体的脂多糖(LPS)进行了电泳分析,以确定其在外包膜(OE)水平的位置。已经收集到的证据表明,OE中存在一些LPS组分,表明该分子的一部分嵌入在膜结构中。此外,还通过单克隆抗血清抗体(Moabs)检测了LPS的血清学特异性;结果表明,LPS结构被赋予血清型的免疫决定因子。这一发现对钩端螺旋体分类的显著相关性进行了讨论。钩端螺旋体的死亡:哥本哈根。硬jo isolierten and gerigenten li多糖(LPS) wurden elektrophoretisch untersuch, um damitre localization in der äußeren hlle zu bestimen。[1] [1] [1] [1] [1] [1] [1] [1] [1] [1] [1] [1] [1] [1] [1] [1] [1] [1] [1] [1]Mittels monolonaler, servarspezifischer Antikörper wurde gezeigt, dasß LPS zu der immunimmuninantantstruktur der Serovare beiträgt。

Leptospiral lipopolysaccharide presence in the outer envelope: Electrophoretic evidence and immunological specificity

Purified preparations of lipopolysaccharides (LPS) extracted from two different strains of Leptospira interrogans have been electrophoretically analyzed in order to determine their location at the level of outer envelope (OE). Evidence has been collected for the presence of some LPS fractions in the OE, suggesting that a part of this molecule is embedded in the membrane structure. The serological specificity of the LPS has been in addition tested by means of monoclonal antiserovar antibodies (Moabs); the results indicated that the LPS structure is endowed of the immunodeterminants of the serovar. The remarkable relevance of this finding for the Leptospira taxonomy is discussed.

Die aus Leptospira interrogans Serovar copenhageni bzw. hardjo isolierten und gereinigten Lipolysaccharide (LPS) wurden elektrophoretisch untersucht, um damit ihre Lokalisation in der äußeren Hülle zu bestimmen. Der Nachweis von LPS-Fraktionen in der äußeren Hülle legt die Annahme nahe, das ein Teil des Moleküls in die Membran-Struktur eingebaut ist. Mittels monoklonaler, serovarspezifischer Antikörper wurde gezeigt, daß LPS zu der immundominanten Struktur der Serovare beiträgt.
