[Detection of pneumococcal antibodies in children with acute pneumonia and pleurisy by an immunoenzyme method].
The samples of sera and pleural fluid from sick children have been analyzed by means of EIA techniques. To detect the time course of antibody production, the antigenic preparations of pneumococci (monovalent capsular polysaccharides, polyvalent polysaccharide vaccine and complex pneumococcal antigen) have been used. Antibody response observed in the forms of pneumococcal infection, studied in this investigation, has proved to be highly variable. It is expedient to determine antibodies to polysaccharide antigens not earlier than on days 10-12 from the beginning of the disease. But, besides the positive dynamics of antibodies, their unchanged level is sometimes observed in the patients at the beginning of the disease. As a rule, there is a coincidence between the dynamics of antibody formation in response to polysaccharide antigens and to complex pneumococcal antigen.
