An enlarged and perfected scheme of typing of Shigella sonnei colicins is based on the knowledge of types of colicins produced by Abbott's types as well as by newly discovered and determined colicin types. A set of specific indicators prepared from E. coli K13 HfrR, E. coli C6 and Shigella sonnei by a selection of suitable mutants and recombinations was used for the typing. Seven new colicin types were determined on typing shigellae found in the field. Type 9A produces colicins E3, Ia, Type 16 produces colicin B, Type 17 colicins B, Ib, Type 18 colicins E2+?, Type 19 colicins E2, Ia, Type 20 colicins E1, Ib, Type 21 colicins E2, ib. The present scheme can be enlarged, when new types are found.
基于对由雅培菌株类型以及新发现和确定的大肠杆菌素类型所产生的大肠杆菌素类型的了解，制定了一个扩大和完善的宋内志贺氏菌大肠杆菌素分型方案。通过选择合适的突变体和重组体，从大肠杆菌K13 HfrR、大肠杆菌C6和宋内志贺氏菌制备了一组特定指标用于分型。在对从现场分离出的志贺氏菌进行分型时，确定了七种新的大肠杆菌素类型。9A型产生大肠杆菌素E3、Ia，16型产生大肠杆菌素B，17型产生大肠杆菌素B、Ib，18型产生大肠杆菌素E2+？，19型产生大肠杆菌素E2、Ia，20型产生大肠杆菌素E1、Ib，21型产生大肠杆菌素E2、ib。当发现新类型时，本方案可以进一步扩大。
