The distribution of IS1, IS600, IS629, IS630 and IS640, present in an Shigella sonnei strain, was examined in strains belonging to various species of enteric bacteria. Four Shigella species including Sh. sonnei contained all IS elements, several of which were in large numbers, and showed species-specific distribution patterns. The other strains contained some of the IS elements in a few copies or none at all, except for some clinical isolates in the Escherichia coli strains, which showed similar distribution patterns to those of the Shigella species, suggesting that the E. coli isolates are closely related to those in Shigella. The IS elements examined may be used to classify various bacterial strains and to identify the Shigella strains and some of the E. coli strains to be isolated from various sources.
对宋内志贺氏菌菌株中存在的IS1、IS600、IS629、IS630和IS640在各种肠道细菌物种的菌株中的分布进行了检测。包括宋内志贺氏菌在内的四种志贺氏菌物种都含有所有的IS元件，其中一些数量众多，并呈现出物种特异性的分布模式。其他菌株含有少量拷贝的部分IS元件或根本不含这些元件，除了大肠杆菌菌株中的一些临床分离株，它们呈现出与志贺氏菌物种相似的分布模式，这表明大肠杆菌分离株与志贺氏菌中的分离株密切相关。所检测的IS元件可用于对各种细菌菌株进行分类，并鉴定从各种来源分离出的志贺氏菌菌株和一些大肠杆菌菌株。
