[Use of the coagglutination reaction for identifying Shigella flexneri]

The data on the use of the coagglutination test for the identification of Sh. flexneri are presented. The influence of different methods for the treatment of antisera on their heterologous reactions was studied and the advantage of coagglutinating reagents was revealed. 9 variants of coagglutinating preparations were obtained; their use made it possible to reduce the consumption of antisera and in some cases avoid their absorption. The problem of Sh. flexneri classification is discussed.
