[Determination of Salmonella typhimurium antigens in the excreta of children with salmonellosis using the passive hemagglutination reaction].

1,390 samples of different excreta obtained from salmonellosis patients have been tested for the presence of S. typhimurium O- and H-antigens. S. typhimurium antigens, detected with the use of antibody diagnostica, have been found to occur more frequently than S. typhimurium cells. Particulate O- and H-antigens capable of agglutinating antibody diagnostica are excreted differently with saliva and urine. Salmonella antigens are best detected in feces in the passive hemagglutination test with the use of antibody diagnostica, but not in the antibody neutralization test. The combination of the passive hemagglutination test, carried out with the use of antibody diagnostica, and bacteriological study considerably enhances the efficiency of diagnosing salmonellosis in children in comparison with bacteriological study alone.
