Abstract

We describe a method for the typing and quantitation of Klebsiella pneumoniae serotype O1 lipopolysaccharide (LPS) based on inhibition in an enzyme-linked immunosorbent assay of a reaction of known O1 LPS antigen and anti-O1 antibody by unknown LPS extracts. Serotype O1 was found in 32% of the 124 K. pneumoniae clinical isolates tested, showing that this serotype is frequent among the eight O serotypes which have been described previously.

摘要

我们描述了一种基于在酶联免疫吸附测定中,未知脂多糖提取物对已知O1脂多糖抗原与抗O1抗体反应的抑制作用,来对肺炎克雷伯菌O1血清型脂多糖(LPS)进行分型和定量的方法。在所检测的124株肺炎克雷伯菌临床分离株中,32%发现有O1血清型,这表明该血清型在先前已描述的8种O血清型中较为常见。
