In the serological study of 17 strains from the collection of Shigella provisory serovars (3873-50, 2000-53, 3341-55, 3615-53, 2710-54, 1621-54) differences in the content of K-antigens were revealed: some of them (3341-55, 3615-53) were in the K-form, others (2000-53, 1621-54) in the O-form, and the rest in the OK-form. No antigenic affinity between the representatives of the enterobacterial group under study was established. The partial composition of O-antigen in bacteria of serovar 2000-53 and antigenically affined E. coli strains, serogroup 06, was studied. E. coli 06 O-antigen was shown to be heterogeneous and had the structure of type a, b--a, c. On the basis of the antigenic structure thus established, as well as its cultural and biochemical properties described in earlier works, serovar 2000-53 should be excluded from the group of Shigella provisory serovars and classified with the genus Escherichia under the designation E. coli 06a. 6b : K? : H--.
在对17株志贺氏菌暂定血清型（3873 - 50、2000 - 53、3341 - 55、3615 - 53、2710 - 54、1621 - 54）的血清学研究中，发现了K抗原含量的差异：其中一些菌株（3341 - 55、3615 - 53）呈K型，另一些（2000 - 53、1621 - 54）呈O型，其余的呈OK型。在所研究的肠杆菌菌群代表之间未发现抗原亲和力。对血清型2000 - 53的细菌以及血清群06的抗原性相关大肠杆菌菌株的O抗原部分组成进行了研究。结果表明，大肠杆菌06 O抗原具有异质性，其结构为a、b型 - a、c型。基于如此确定的抗原结构以及早期研究中描述的其培养和生化特性，血清型2000 - 53应从志贺氏菌暂定血清型组中排除，并归类于埃希氏菌属，命名为大肠杆菌06a.6b : K? : H--。
