[Assessment of the diagnostic effectiveness of antigenic preparations from Sonne shigellae].

The authors studied the diagnostic possibilities of 4 diagnistic agents from Sh. sonnei. A total of 1500 from 1122 persons were investigated. Specificity and sensitivity of the diagnostic agents from Sh. sonnei were determined. Methodical priciples of the objective assessment of the diagnostic efficacy of the antigenic preparations in the controlled epidemiological trial were elaborated. A possibility of establishment of the etiological diagnosis of Sonne dysentery in the passive hemagglutination or blast agglutination tests by the results of testing with the diagnostic agents of the serum obtained from the patient once or by determining the dynamics of the antibody titre rise in coupled serum portions was not great.
