title: [The determination of antimeningococcal antibodies in the saliva of healthy people].
abstract: The determination of antibodies to the group-specific polysaccharide of group A meningococci (PS-A) in the saliva of 162 healthy persons at different seasons of the year revealed that antimeningococcal antibodies could be detected in all examines. The range of concentrations of antibodies to PS-A varied between 0.1 and 33.0 U/ml. The comparison of antibody content with the levels of morbidity in meningococcal infection and carriership made it possible to determine two threshold levels of antibody concentration: 9.0 U/ml and 18.0 U/ml.
