Chlamydial antibodies in Danish children

Chlamydial antibodies in titers of greater than or equal to 1:16 were found in 24 percent of 803 randomly selected healthy Danish school children. A higher prevalence of antibodies was found among the girls in all the age groups. The prevalence of antibodies increased significantly with increasing age up to puberty. The findings indicate a wide distribution of infections with Chlamydia trachomatis in childhood. The possible clinical expression of these infections is generally unknown.
