title: [Further research of antibodies anti-"N. meningitidis" among healthy population of Bari (southern Italy) (author's transl)].
abstract: Research of antibodies anti-N. meningitidis serogroups A, B, and C was carried out on 248 healthy children 7 months-10 years aged by indirect hemagglutination, to determine the age of their initial demonstration into the serum and the time of their clearness, besides the diffusion of antibodies within the infantile population. Antibodies against one or more serogroups of N. meningitidis were detected already in the second half-year life in 73 percent examined children. Frequence of antibodies is progressively increasing in the last years until to findings about 90-100%. Antibodies against N. meningitidis serogroups A were detected more frequently, and in a less degree, the ones against serogroup C. Research of antibodies after 2 and 12 months was repeated on 84 subjects; for the most part of these the antibody titre was the same.
