title: [The characteristics of the serological diagnosis of meningococcal infection in children in the 1st years of life].
abstract: The results of clinico-immunological examination of 181 children, aged 1 month to 6 years, with generalized forms of meningococcal infection are presented. In children under observation antimeningococcal antibodies to group-specific meningococci of the main groups A, B and C were determined over the course of the disease by passive hemagglutination (PHA) test and enzyme immunoassay (EIA). The level and frequency of seroconversion were found to depend on the patient's age and the severity of the clinical course of meningococcal infection. Antibody level was found to increase simultaneously with respect to several meningococcal polysaccharides: A, B in 18.5% and A, B, C in 3.3% of cases. In the clinical interpretation of data obtained in the PHA test and EIA not only the patient's age, the form and duration of meningococcal infection, but also serotherapy should be taken into consideration, as the latter may distort the serological results.
