A study was made of 239 strains of enteropathogenic escherichia 0151:K-- isolated in various regions of the USSR from patients with the clinical diagnosis of dysentery, gastroenteritis, intestinal coli-infection: a standard strain of the international collection of escherichia belonging to the given serological group was also studied. There was shown an increase in the role of these microorganisms among the enteropathogenic escherichia recorded at the territory of the USSR; they occupied the third place by the frequency of isolation after the serological group 0124:K72 and 0111:K58. There was established a common nature of the enzymatic characteristics of escherichia 0151:K--with shigellae by the absence of lactose, sucrose, inosite, adonite fermentation, the presence of gasless, immobile variants containing no lysin decarboxylase, and a possibility of rapid differentiation from shigellae in the use of acetate medium. Among the escherichia 0151:K--there was revealed the presence of 5 biotypes by the capacity to gas-formation in glucose, arabinose, sorbit, dulcit fermentation, and decarboxylation of lysin and ornithin; three biotypes are described for the first time. Industrial issue of the agglutinating serum 0151:K--is necessary to provide the diagnosis of these microorganisms at the territory of the USSR.
对苏联各地区从临床诊断为痢疾、肠胃炎、肠道大肠杆菌感染患者中分离出的239株肠致病性大肠杆菌O151:K--进行了研究；还研究了属于给定血清群的国际大肠杆菌菌种保藏中心的标准菌株。结果表明，在苏联境内记录的肠致病性大肠杆菌中，这些微生物的作用有所增加；按分离频率计算，它们仅次于血清群O124:K72和O111:K58，位居第三。已确定大肠杆菌O151:K--与志贺氏菌在酶学特征上具有共同特性，即不发酵乳糖、蔗糖、肌醇、阿东醇，存在无气体、不运动且不含赖氨酸脱羧酶的变体，并且在使用醋酸盐培养基时有可能与志贺氏菌快速区分。在大肠杆菌O151:K--中，根据在葡萄糖、阿拉伯糖、山梨醇、卫矛醇发酵中产生气体的能力以及赖氨酸和鸟氨酸的脱羧作用，发现了5种生物型；其中三种生物型是首次描述。为在苏联境内诊断这些微生物，有必要生产O151:K--凝集血清。
