[Specific antigens of the causative agents and their antibodies in the circulating immune complexes in acute dysentery].

The level of circulating immune complexes has been determined in 53 patients in the dynamics of the disease. For the first time circulating immune complexes have been found to contain Shigella sonnei K-antigen and Shigella flexneri O-antigen, as well as IgA, IgG and IgM to Shigella. Shigella antigens can be detected from the first week of the disease, and their occurrence does not depend on the level of circulating complexes in patients blood serum.
