title: [Quantitative determination of the soluble O antigen of Salmonella serogroup B and of specific antibodies in different classes by using immunoenzyme analysis].
abstract: The results of measurements of S. typhimurium O-antigen and specific IgA-, IgG- and IgM-antibodies in 115 serum samples from patients with salmonellosis induced by group B salmonellae are analyzed. As determined in this study, the concentrations of IgA-antibodies ranged 0-15 micrograms/ml, the minimal diagnostically significant value being 3.6 micrograms/ml; the concentrations of IgG-antibodies ranged 0-13 micrograms/ml, the minimal diagnostically significant value being 1.3 micrograms/ml; and the concentrations of IgM-antibodies ranged 0-50 microgram/ml, the minimal diagnostically significant value being 5.0 micrograms/ml. The minimal diagnostically significant concentration of O-antigen, determined in selected serum samples obtained from healthy donors, was 0.1 microgram/ml. There is a significant correlation between the concentrations of IgA-, IgG- and IgM-antibodies, but the concentrations of these antibodies do not correlate with the concentration of soluble O-antigen. The study showed that the simultaneous determination of S. typhimurium O-antigen and specific antibodies in the material under test significantly enhances the effectiveness of the serodiagnosis of the disease.
