| Abstract: | The results of the determination of antibodies to lipopolysaccharide (LPS) in 270 patients with different forms of meningococcal infection and in 816 healthy persons by means of the passive hemagglutination test are presented. The role of antibodies to LPS in the formation of humoral immunity to meningococci in sick children and adults is shown. Different forms of meningococcal infection have been found to have their specific features of the accumulation of antibodies to LPS. As revealed, the time of the sanation of liquor and the level of antibodies to LPS are unrelated, which indicates that antibodies to LPS may play some role in the pathogenesis of meningococcal infection. |
