[Quantitative determination of the soluble antigens of intestinal bacteria using a method of immunoenzyme analysis. I. Processing of the parameters of the method].
The parameters of the assay based on the quantitative evaluation of the neutralization of specific antibodies by the antigen under study and the subsequent detection of free antibodies on the fixed reference antigen with the aim of the quantitative determination of the specific O-antigens of Salmonella, groups D, B, C1, as well as those of Shigella sonnei and Shigella flexneri, have been developed. The proposed method makes it possible to detect the O-antigen of the causative agent at concentrations of 0.001 micrograms/ml to 100 micrograms/ml.
