[Serodiagnosis in salmonelloses].

A method for preparing antigenic hydrosol diagnostic agent for hydrosol agglutination test is suggested. Efficiencies of hydrosol agglutination and passive hemagglutination tests in detection of antibodies to salmonella are compared. Arbitrary diagnostic titers are determined, diagnostic value of hydrosol agglutination test is assessed, time course of accumulation of specific antibodies is traced, and optimal terms of serological diagnosis of salmonellosis in patients of different age are determined.
